Warm-Up: Factor by GCF 1. 16x 2 – 8x 2. 10x – 10y
FACTORING POLYNOMIALS FACTOR BY GROUPING METHOD
10x – 10y
8r 2 – 24r
Steps to Factor by Grouping 4 terms 1. Group the 1 st two terms and the 2 nd two terms 2. Factor out the GCF of each group 3. Write down the common parenthesis 4. In another parenthesis, write the GCFs 5. Check to see if the parenthesis can factor again
x 3 + 7x 2 + 2x + 14 Let’s group the terms to find common factors! x 3 + 7x 2 + 2x + 14
x 3 + x 2 + 5x + 5
y 3 – 14y 2 + y - 14
m 3 – 6m 2 + 2m - 12
ad + 3a – d 2 – 3d
