Factoring Using Quadratic Equation

Solve by factoring:

x² + 6x + 20 = -3x

• x = -2, x = -10

• x = -3, x = -4

• x = -4, x = -5

• x = -4, x = -6

Factor x²-6x-40

• (x-10)(x+4)

• (x+10)(x-4)

• (x-8)(x+5)

• (x+8)(x-5)

Solve using any form of factoring or Quadratic Formula

x² + 6x + 9 = 0

• x = −3, 3

• x = −3

• x = 3

• No Solution

Solve the equation using the zero product property.

3x(2x - 4) = 0

• x = -1/3 or x = -2

• x = 0 or x = 2

• x = 0 or x = -2

• x = -1/3 or x = 2
