Quadratics Practice Test

Solve by factoring.

x² + 2x - 24 = 0

• x = -6, x = 4
• x = 6, x = -4
• x = 12, x = -2
• x = 8, x = -3

Use the quadratic formula to solve 2x² + 2x - 12=0.

• -2, 3

• 2, 3

• 2, -3

• -2, -3

Determine the values of a, b, and c for the quadratic equation:

4x² – 8x = 3

• a = 4, b = -8, c = 3

• a = 4, b =-8, c =-3

• a = 4, b = 8, c = 3

• a = 4, b = 8, c = -3
