Factoring Solving Quadratics

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

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 by factoring:
x² - 6x + 5 = 0

• k = 4, -6

Solve for the values of x:
(x - 3)(x + 6) = 0

• { -3, -6 }

• { 3, -6 }

• { -3, -6 }

• { 3, 6 }

Solve using Zero-Product Property.
(x+4)(x-3) = 0

• x = 4 and x = -3

• x = 2 and x = 1

• x = -4 and x = 3
