Use the square root property to solve the Quadratic Equation.
x² = -49

• ± 7

• -7

• ± 2401

• ± 7i

Solve the equation using the zero product property.
(x- 9)(x + 3) = 0

• x = 3 or x = 9

• x = 3 or x = -9

• x + -3 or x = 9

• x = -3 or x = -9

Solve the equation using the zero product property.
3x ( 2x - 4) = 0

• x = -1/3 or x = -2

• x = 0 or x = 2

• x = 0 or x = -2

• x = -1/3 or x = 2

Solve the equation by factoring.
x² - 35x - 36

• -1, 36

• 1, -36

• -6, 6

• -6

Miked solved the equation x² + 8x = 14 by completing the square. Which of the following equations is part of the correct solution.

• (x + 4)² = 14

• (x + 4)² = 18

• (x + 4)² = 30

• (x+ 4)² = 30

What should you do first in solving this equation?
x² + 6x - 13 = 3

• Get factored form

• Write down: a=1, b=6, c=-13

• Make it equal 0 by subtracting 3 on each side

• Type it all in a calculator.

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
