Factoring/Solving Quadratics

Given the quadratic equation:  x² + 4x - 40 = -8
Find a=____ b=____ and c= ____

• -10 & -4

• -4 & 10

• -8 & 4

• 8 & -4

Factor:
x² - 10x + 24

• (x - 6)(x - 4)

• (x + 6)(x + 4)

• (x - 12)(x + 2)

• (x - 8)(x - 3)

Solve
a² + 2a - 24 = 0

• a = -6, 4

• a = 6, -4

• a = 12, -2

• a = 8, -3
