Solve
x² + 9x + 20 = 0

• x = -2, x = -10

• x = -3, x = -4

• x = -4, x = -5

• x = -4, x = -6

Solve

(n +7)(n + 9) = 0

• n = -7; n = 4

• n = 7; n = -9

• n = -3; n = 10

• n = -7; n = -9

What are the zeros of the function below?

f(x)=(x - 6)(2x + 4)

• x = -6, x = -4

• x = 6, x = -2

• x = 4, x = 6, x =2

• cannot be determined

• x = - 4 and x = - 5

• x = 20 and x = - 9

• x = 4 and x = 5

• x = - 4 and x = 5

• x = - 5 or x = - 7

• x = 5 or x = 7

• x = - 35 or x = - 1

• x = - 9 or x = - 4
