• 1 and -12

• -1 and -9

• 1 and -9

• 1 and -1

What are the solutions for the equation 2x² + 16x = 18

• x = -1 and x = 9

• x = -9 and x = 1

• x = 2 and x= 18

• x = 2 and x = 16

Solve using square roots.  x² - 4 = 0

• x = 2

• x = 2 or -2

• x = -2

• x = 16 or -16

Solve by factoring

x² + 10x = -25

• x = -5

• x = ±5

• x = 5

• x = 0

Which equation is CORRECT for the graph?

Solve the equation: 
5x² - 35x + 60 = 0

• x = 3,  -4

• x = -3,  4

• x = 3,  4

• x = -3,  -4

Find the roots of this equation
x² + x - 6 = 0

• 4, -1

• 3, -2

• -6, 1

• 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

• Factor

• Subtract 6 from both sides to set the equation equal to 0

• Set each factor equal to 0

• Combine like terms
