Here are some additional HW problems to work on for 6.2 (from the assignment sheet). I'll pull TWO of these for the quiz tomorrow, and come up with the other three.

I'm also attaching the assignment sheet again so that you can BOOKMARK IT!

There are a bunch of practice problems for EACH section that we do in the course.

Lemme know if you need any help!! I'll be @ school at 730 and available during lunch / passion time tomorrow.

Won't have time to share with you in class, but check this out!

Check out this video about The Fundamental Theorem of Algebra, tomorrow's concept.

5.5 Theorems bout roots of polys

Here is a link to the slides..in here are screenshots from the text which pretty much break down every single step for you for both synthetic and long division. Again, it is imperative that you know how to do synthetic division to move on in this chapter. You need to practice outside of this course in order to be successful. I'd say a minimum of 30 minutes a day, even just looking over the notes and working on the problem sets. It is evident how much time outside of class some of your spending on the material. You are about to fall very behind.

I have attached a copy of the exact same format of the quiz, but different questions. DO NOT take this quiz until you are sure that you understood the lesson (look over notes, try some problems). You want to be able to complete this in less than 30 minutes. Time yourself. Take note of this time. Write it down on your quiz tomorrow and see if you can beat it (accurately).

This course is all about shortcuts and being efficient...one of the main objectives is to recognize patterns. I have said all along how having a strong basis is going to be good for this course. Notice today how we didn't even need to use synthetic division when we were able to factor the polynomial? For example, x^2-9 by x-3. We know it has to be x+3.

That will save you some time so that you can focus on the other concepts.

I hate to end on a sour note, but we are now in week 11 of the 18 week semester. If you are not passing the course by week 16, you will fail the course. You will not pass part B without passing part A.

As always, email me if you need anything.

I moved the factoring video / Worksheet has been moved to the top, check it out if you need help!

Some of you asked for a worksheet to practice your factoring. Here are a bunch with solutions for ya :).

I also found a video about the mistake method in case you need to review. I'm telling you, factoring is going to be crucial for you in this polynomial section.

5.1 Polynomial Functions

Hi everyone,

Grades are now updated, including both midterm scores and your effort score.

NOBODY IS IN THE HOLE YET. Sorry for the caps, but if there is anything I wanted you to see it is that. This is only 1/4 of the way through the school year. If you are sitting at a low grade, it is not too late to turn it around. It is your responsibility to do that. I am here to help you, but you need to be willing to put the work in.

Overall, I was pleased with the performance on the exams. There are some small things we need to work on. As I said, I put more problems on there than you were expected to complete. This is not to be a jerk. This is to see what you are capable of. Did you notice the mix of questions on the exam? It was very evenly distributed amongst the chapters, aside from part 2 being exclusively chapter 4 due to time constraints. I want you to be well-rounded in your mathematical ability.

This class will help you strategize/problem solve in life. One day you will realize how important it is. Not just so I can say I told you so either.

Some statistics about the class.

The average grade on...

Part A Midterm - 73.43%

Part B Midterm - 69.51%

Overall Class Average - 75.61%

Again, if you are sitting below the class average, you should be a bit worried. You need to communicate with me ASAP so that we can setup a plan to get you back on track.

I left everyone a comment on their effort grades. I tried give something positive / something to improve upon, and even gave some warnings, so be sure to check them out.

Side note: I think that you were very honest in your feedback / evaluation, but some of you were a bit harsh on yourself. You are all great individuals. I know most of you are working hard and giving the class 100%. Take a load off (see song). This is going to be a difficult course, but all of you are capable if you put the work in!

Please leave me a comment back, even if its just an "ok" so I know that you've read my feedback. I'll discuss the feedback everyone gave me on Monday.

Good luck on your finals tomorrow. Enjoy your long weekend!

Some data for you about the class:

The highest grade in the class is a 110.73% - AMAZING job to that student!

The mean grade in the class is a 75.02% - I am okay with this average. I can see that a lot of you are working hard, but I'd like to be closer to the 80% mark. I appreciate your hard work. Keep it up!

The median grade in the class is a 70.17% - With the median being less than the mean, there is more data to the left of the mean than to the right. So, there are more students with grades lower than 70.17%. This is not a good statistic. We are almost at the halfway mark for the first semester. There is the midterm coming up that can be a huge boost for you. Or, quite honestly, it can crush you. If you don't pass part A, you won't be able to do part B. It's a waste of a school year. Don't let this happen to you.

The standard deviation is 17.31%. I can have one of my statistics students explain this for you tomorrow for bonus points :)

Keep up the great work everyone! Check out the slides and the problem set today. It will do you well.

As I said in class, you are not required to solve the system of equations problems via a matrix. It is your choice which method you use, I just need to see the work.

Enjoy your Saturday night!

Prob Set Solutions

Just left comments on all problem sets. I will be available via email if you have any questions tonight. Don't forget, have it in before 11:59 PM. Any changes made after that will be reverted back.

Note: Hate having to say this but I just saw someone with an F in the course and 100% on the latest problem set.

I know that there are online calculators that can solve a system of three variables for you. I'm fine with you using this to check your answers. If I catch you doing this, it is against the academic integrity policy at SET, and you will fail the assignment (or the entire course). It will be evident on an exam that you cheated. Don't do it.

Sorry for an additional post tonight but...

I had some amazing African food (Flavors of East Africa - you NEED to try it) while watching the sunset with a friend from high school who is visiting the city. She was complaining about her 9-5 and all I could do was brag about how happy I am at my job because my students rock.

I know said I wouldn't comment on problem sets, but I couldn't help it after that conversation. You guys deserve it. Even if you turned it in already, look it over.

See you tomorrow!

I went to go look over the problem set to leave comments, but I realized that you can easily check your answers with desmos. For me, it is important to understand the relationship algebraically and graphically, so I find it beneficial to see the graph.

It's important that you use desmos as a tool. When I made the answer key, do you think I was using elimination to solve the system? Of course not, I graphed them on desmos and looked for their intersection. However, if needed, I can still rely on my algebra skills to solve it by hand. Don't use it to cheat. Come test time, you'll be paddling against the current. That's a system you can't solve (HA!) ;)

Apologize for the low energy today, but yesterday was exhausting. See you all tomorrow!

Comments have been shared with you. Few things:

Some of you still have NO NAME on your document!! Come on!!!

Be sure to use the EQUATION EDITOR. Some of you have things like 3/2x . That is wrong. We have x in the denominator there. What you really mean to say is (3/2)x. That looks ugly though, and is why we use the equation editor.

Make sure you are putting { } around your sets.

Division by 0 / negative square root are both undefined.

For Direct Variation, 10=3k . you need to solve for k, then input that value into y=kx

Everyone is saying that the point (3,4) is on their line (where you're given a slope and a line), which is impossible. How are you getting this? I can't quite figure it out. Check your work!

0 / 2 is zero. 0 / anything (except for 0) is 0. So for that last equation, you can leave out the 0x.

Nice work! See you tomorrow.
