1. Do Now-if you have Bonus point, hand them into the basket
Have your green sheet and HW out on your desk
Do one problem in each category:
Give the prime factorization of each of the following:
a4b3c
Find the GCF of each of the following:
, x2y4, 36x5y3
Factor out the GCF:
x2y4 + 36x5y x2 – 7x + 21

2. Factoring by Grouping
You can try to factor by grouping when your polynomial has four terms.

3. How to Factor when we have 4 Terms!
Always look for a GCF first!
Then separate your terms in pairs using parenthesis.
Find the GCF for each binomial.
Your answer will be (GCF’s)(leftovers).
***Your leftovers must match***

4. Factor: 12x3 + 3x2 + 20x + 5

5. Check Answer: (3x2 + 5) (4x + 1)
Box or FOIL Method
12x3 + 3x2 + 20x + 5

6. Factor: a2x – 4a2c + 15x2 – 12xc

7. Factor: v3 – 12v2 – 5v + 15

8. Factor: xy – 12b2 + 14xb – 18by

9. You Try: x2 - 8xy - 2y2 + 2xy

10. Error Analysis
Factor 20p3 + 40p2 + 15p (20p3 + 40p2) + (15p + 30) 20p2(p + 2) + 15(p + 2) (p + 2)(20p2)
