Factoring by GCF and Grouping
Algebra II CP
GCF
Greatest Common Factor
a. x² - 6x b. 15x³ + 10x² - 5x
Grouping
a. 6xy – 8x + 15y – 20
b. 12x² - 15xy – 16x + 20 y
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
