Solving Quadratics (Mixed Practice)

Solve the quadratic function:

h(x) = x² + 3x - 18

• x = -3 and x = 6

• x = 3 and x = -6

• x = -9 and x = 2

• x = 9 and x = -2

Solve by taking square roots:
k² - 6 = 43

• k = √37
• k = 37 or - 37
• k = 7, k = -7
• no solution

Find the zeros of the quadratic function:

f(x) = 2x² - 3x - 2

• x = 1, x = -1

• x = -1/2, x = 2

• x = 1/2, x = 2

• x = 1/2, x = 1

Find the solutions of the quadratic equation:

5x² + 32 = 28x

• x = 8, x = 4/5

• x = 8/5, x = 4

• x = 8/5, x = -7

What are the zeros to the equation

x² - 2x = 8?

• x = 2 or x = -4

• x = 1 or x = -8

• x = 4 or x = -2

• x = 8 or x = -1

Use the graph to determine the solutions.

• -1 and -3
• 1 and -3
• 1 and 3
• -1 and 3
