Last Bit of Notes From Thursday!

Section 6.3 Continued - What to do if you can't factor out a GCF:

And that's the end of the information that we covered last week. This stuff will be on the test on Thursday, so make sure you contact me if you didn't understand anything in the videos.

See you Tuesday!

Notes and Homework From Thursday, December 6.

Hi Guys,

Sorry things are taking too long to post. If you are having trouble viewing the videos please let me know and save me the pain of trying to post them.

On Thursday night I finished off Chapter 6 - it was more on factoring.

The homework is:

6.2 Page366: 1-6 all, 11, 12, 21
6.1 Page 360: 31, 32, 35, 41, 42
6.3 Page 374: 1, 2, 3, 5, 11
6.4 Page 379: 2, 3, 4, 5, 7
6.5 Page 391: 1, 2, 5, 11, 13, 35

I'm going to try to get all the notes posted this weekend.

I also passed out the study guide for the next test. I left copies with Judy in the CTC office on Foster (down at the end of the hall on the left if you keep walking straight past the classroom) for those of you who are absent. If you can't make it to the office by Tuesday I will give you your copy in class. Or you can email me and I can try to scan you a copy, but your primary focus over the weekend should be trying to learn as much as possible from the notes online, and trying not to get too far behind on the homework.

The test date is next Thursday December 13.

The test will cover material from Chapters 5 and 6. This homework is the last homework assignment, and the material covered on Thursday is the last bit of new material that will be on the test.

Next week my plan is this:

Tuesday I will cover a few topics that will significantly help you in college algebra, but that won't be on the test. Then I will do a test review and answer any questions I need to answer to get those of you that were absent this week caught up.

Thursday will be the test.

See you on Tuesday!

Notes from December 4 Continued - Chapter 6.1

I'm sorry it is taking me so long to load these videos...they are coming I promise!

The second half of your homework assigned on Tuesday is over section 6.1, which is factoring. Pretty much all of chapter 6 is factoring.

An Introduction to factoring:

Finding the GCF:

Factoring Out the GCF:

More examples of factoring out the GCF:

What to do when the GCF is a polynomial:

This is everything you need to know to finish the homework from section 6.1 assigned on Tuesday.

Notes from Tuesday, December 4, 2007

Hi Everyone,

I tried to keep class short today since I knew I would have to post everything online too, and I wasn't sure if I would be able to get all the notes up. I covered sections 5.6 and 6.1.

The homework was as follows:

5.6 pg 341: 13-18 all
6.1 pg 360: 3, 6, 7, 17, 20, 23, 24, 29, 30

Section 5.6 was the section talking about polynomial division. The homework is over diving a polynomial by a binomial. The book teaches you to use long division. I prefer using synthetic division because it is easier. I suggest ignoring the book and doing it my way, but that's your choice. I will use synthetic division in the examples below:


Divide a Polynomial by a Binomial: Example 1

I forgot to mention that every time you multiply, you write the number above the line, and every time you add, you write the number below the line.

Synthetic Division: Example 2

These videos are taking a LONG time to load on the page (over an hour for this one) so I will be posting them SLOWLY over the next few days. I may have to limit the number of examples I show you. Keep checking back!!

Synthetic Division: Example 3

video

Rules for Using Synthetic Division - This is useful to know for College Algebra, but it will not be on the test.

At this point I have uploaded all the notes on synthetic division. You should be able to complete the homework for section 5.6 now. I have a few more examples in my notes. Let me know if you need to see them.

Ok I lied, there was one more set of notes for synthetic division.

Now I'm finished with synthetic division.
