The solutions of the quadratic equation

x²+2x-15=0 are (hint: find the zeros) FACTOR

• x = 3 or x = 5

• x = 5 or x = -3

• x = -5 or x = 3

• x = -3 or x = -5

Solve by factoring. (what do they have in common)

n² - 2n = 0

• n = 2 and 0

• n = -2 and 0

• n = 2

• n = 0

Solve by factoring.

b² + 2b - 24 = 0 (hint: find the zeros) FACTOR!

• x = 6 or x = -4

• x = -6 or x = -4

• x = 6 or x = 4

• x = -6 or x = 4
