Solve the equation by factoring.

Solve by factoring: x² + 3x - 18 = 0

• x = -3 and x = 6

• x = 3 and x = -6

• x = -9 and x = 2

• x = 9 and x = -2

Factor: x²+10x+16

• (x+2)(x+8)

• (x-2)(x-8)

• (x+1)(x+16)

• (x+6)(x+10)

Solve by factoring: x² - 9x + 20 = 0

• x = -4 and x = -5

• x = 20 and x = -9

• x = 4 and x = 5

• x = -4 and x = 5

Solve for a by factoring.

a² + 2a - 24 = 0

• a = -6 and a = 4

• a = 6 and a = -4

• a = 12 and a = -2

• a = 8 and a = -3

Solve by factoring:
 x² - 9x + 20 = 0

• x = -4 and x = -5

• x = 20 and x = -9

• x = 4 and x = 5

• x = -4 and x = 5

Solve the equation by factoring:

x² - 6x = -8

• x=2 and x=4

• x= -2 and x= -4

• x= -2 and x=4

• x=2 and x= -4

Factor:  x² + 9x + 18

• (x + 3)(x + 6)

• (x - 3)(x - 6)

• (x + 9)(x + 2)

• (x + 3)²
