Solving Quadratics and Factoring the GCF

Solve for x. (x + 8)(x + 2) = 0

• x = -8 and x = 2

• x = -8 and x = -2

• x = 8 and x = 2

• x = 16 and x = -16

Solve for x. x(x + 2) = 0

• x = 0 and x = 2

• x = 0 and x = -2

• x = 0 and x = 4

• x = 1 and x = 2

Solve for x. 3x(x + 2) = 0

• x = 0 and x = 2

• x = 0 and x = -2

• x = 0 and x = 4

• x = 1 and x = 2

Solve using square roots.
