Algebra 1C Ch. 10 (Part 2) Practice Test

Solve (x + 12)(x - 4) = 0

• x = -12 or x = 4

• x = 12 or x = -4

• x = 0 or x = 16

• x = -16 or x = 0

Solve (x - 9)(x + 1) = 0

• x = 9 or x = -1

• x = 9 or x = 1

• x = -9 or x = 1

• x = -9 or x = -1

• x = 3 or x = -4

• x = -3 or x = 4

• x = 2 or x = -6

• x = -2 or x = 6

• x = 4 or x = -2

• x = 2 or x = -4

• x = 4 or x = 2

• x = -4 or x = 2

• x = 1, x = -0.2

• x = -1, x = 0.2

• x = 0.1, x = -2.7

• x = 2.7, x = -0.1
