Factoring Quick Check

Factor
x² - 5x - 36

• (x - 4)(x + 9)

• (x - 6)(x + 6)

• (x + 4)(x - 9)

• (x -12)(x + 3)

What is ALWAYS the first step when factoring?

• Look for the GCF

• Write a, b, and c

• Difference of squares

• Group

Factor:

2x² + 3x - 9

• 2(x + 3)(x - 3)

• (2x - 3)²

• (x + 3)(2x - 3)

• (2x + 3)(x - 3)

x² - 16

• (x + 4) (x - 4)

• (x + 8) (x - 2)

• (x + 4)²

• x + 4(x - 4)
