Review 5b • pp. 284-285
At a minimum, #1-65 (÷ 5)

You will be able to use your Interactive Notebook, so you might want to create a summary page. But honestly, working the problems is the most valuable preparation.

CNotes 5.6 • Factoring Trinomials

Homework
No New Homework other than begin getting ready for Friday's test.

Cornell Notes
Today in class we went over yesterday's homework, and then we took notes over the factoring techniques that we have been using over the last several lessons, techniques for factoring trinomials.

Here are the notes we took today. Set them up in Cornell Note format

Topic... 5.6 Factoring Trinomials
Essential Question... How do we factor trinomials?


Factoring Trinomials with no initial coefficient.

x^2 ± bx ± c





Factoring Trinomials with an initial coefficient.
ax^2 ± bx ± c

HW 5.6c • Due Monday, December 8

Friday, December 5, 2014
Set 5.6c • pp. 272-273
#48-84 (every other pair)

1.  Categorize them by writing the problem in the appropriate box.

2.  Factor the problem completely

For example, 
#48. 14w^2 - 29w - 15 would be written in the box labeled ax^2 ± bx ± c

HW 5.6b • Due Friday, December 5

Set 5.6b • pp. 272-273
#19–34, 43–44 (all)

Today we learned how to factoring trinomials in the form of
ax^2 + bx + c.

Look at the video and the steps below:



Here are the basic steps which are illustrated on the video:
1.  Transform Trinomial into a Quadnomial 
      a.  Using X-Factor Method
      b.  Middle term goes in upper section
      c.  1st term × 3rd term goes in lower section
      d.  Find the two numbers that work
      e.  Rewrite trinomial as quadnomial

2.  Factor Quadnomial using the Factor by Grouping Method

Video • Factoring Trinomials • The X Factor Method

Here are four videos that illustrate the X-Factor Method of factoring trinomials:

Example #1:  x^2 + 9x + 20 
Example #2:  x^2 + 5x – 36
Example #3:  x^2 – 5x – 14
Example #4:  x^2 – 11x + 24

Example #1:  x^2 + 9x + 20

 

Example #2:  x^2 + 5x – 36


Example #3:  x^2 – 5x – 14


Example #4:  x^2 – 11x + 24


HW 5.6a • Due Thursday, December 4

Set 5.6a • pp. 272-273
#1–18, 35–42, 45–47 (all)


A few are not factorable.

I want you to use the X-Factor method that we went over today in class. I don't know if I will have a chance to put a video together to explain the method. In the meantime, watch the following video and follow this teacher's method (which is where I got it). Click

Test Corrections

For those of you who were absent...
Today, we went over the test, and then took notes on Solving Second Degree and higher equations.
