GCF

Greatest Common Factor

a. x² - 6x b. 15x³ + 10x² - 5x

Page 3: Factoring by GCF and Grouping

Grouping

a. 6xy – 8x + 15y – 20

b. 12x² - 15xy – 16x + 20 y

Page 4: Factoring by GCF and Grouping

Factoring to Solve

a. (2x + 1)(x – 5) = 0

b. 12x² = 36x

Must set everything equal to zero first.Factor, then solve.

Ex last one:

Solve each equation.

a. 4a² = 10a b. x² + 3x + 4x + 12 = 0
