1. Warm-up Find the GCF for the following: 36, 63, 27 6x2, 24x
15x3, 25x2, 55x

2. Factoring using GCF

3. Dividing a Polynomial by a Monomial
Steps
Divide the coefficients
Subtract the exponents of common variables

4. Examples: Divide.
1. 5x x x2 + 4x 4. 9b2 – 15b 2x 3b

5. Examples: Divide.
5. 10x2y2 + 5xy 6. 27x2 – 21y2 5xy x + 24xy 8. 4x3 + 2x2 – 6x 8x 2x

6. GCF Factoring
Factoring is the reverse of multiplying. It is similar to dividing. So when we are factoring out the GCF of a polynomial, we will divide each term by the GCF.

7. Examples: Factor.
1. 9x x2 – 21x 3. 18x6 + 12x x3 – 25x2 + 55x

8. Examples: Factor.
5. -2m4 + 14m2 – 6m 6. -5x2y + 35xy 7. -2x2 + 10x – x2y2 + 32xy3
