Polynomial Unit TEST REVIEW

Please consider the resources below when preparing for your unit test on Tuesday, November 21st.

- Use those "mega factoring" sheets. 

- Try this worksheet for extra practice with the greatest common factor. Here are the answers.

- Did you struggle on the quiz that you got back today? Here's the homework that you might have opted not to do...

- Here is some (online) practice on the remainder theorem and something being a factor or not

- Here is a copy and answers to a review available in class on Friday (11/17). You may need a book for some of the problems.

- Here are the answers to the graphing WS given out in class on Wednesday.

FACTORING IS THE GREATEST!

Teach me how to factor!

Remember - factoring is the backbone of this unit!

Here is a calendar for what our plans look like before Thanksgiving Break...

Greatest Common Factor

Today in class we took a quiz over the remainder theorem & dividing polynomials. The highest score you can receive on this is a 2. There will be another opportunity next week for you to show further understanding of this topic, if need be.

After the quiz, we worked through the greatest common factor. 

Here is the Powerpoint (without my notes).

Here is the optional assignment.

Here is a video you can watch if you need more support! 

Polynomial Division

Today we worked on Polynomial Division. If you are still feeling frazzled, here is a video that explains the method we used. I'm loving the shirt that the instructor is wearing!

If videos aren't your thing, here is a written out post with some examples. *NOTES TO FOLLOW!*

If after looking at those two resources, and checking back through your notes, you're STILL stuck, PLEASE COME IN FOR HELP. We are available before and after school; sign-up sheet is on the board.

Post-Graphing Test

Hi there!

I see that you're done with your graphing mini-test. Right on!

Here are some videos I'd like you to watch in preparation for our next unit. Watch these, and complete the worksheet I have for you. This is critical knowledge for our next unit. Seriously!

Video 1
Video 2
Video 3

*Disclaimer: If you have another way that you can multiply polynomials, and you are successful, feel free to use it. I will be using the box method for everything in this unit - both multiplying and dividing. It can't hurt you to be able to do this method, too! 

Test Next Week

Our first unit test will be on Tuesday, October 3rd. This test will cover both functions and inverses. If you're not sure what this means, consult your pink sheet.

Suggested review problems (all from textbook):

Pg. 26: 14

Pg. 34: 1

Pg. 87: 7-9

Pg. 124: 14

Pg. 125: 1 (a-c), 2 (a-f), 4a

Pg. 295: 5

Answers can be found HERE.

Review I mentioned in class can be found HERE. Answers are available in my room.

Struggling Lately?

If you've been struggling with the content the past few days, here are some videos that may be of interest to you:

Quiz on Tuesday

Hi there,

Great week in Algebra 2! I appreciate everyone's hard work in class.

You have another quiz on Tuesday. It will be the FIRST opportunity for domain, range, and composition of functions. It will be the SECOND opportunity (if you need it) for tables & writing functions from tables.

Here is the powerpoint from today. 

There are potential practice examples at the end of the ppt - all from your book!

First Checkpoint!

The first checkpoint will be on Thursday, August 31st. It will cover the following topics:

• Difference tables
• Writing functions from tables
• Writing functions from written descriptions

Looking for a study guide? Try the homework! 😁

Welcome!
