• x = -1.5 and x = 5

• No Solution

• x = -5 and x = 1.5

• x = 0.7 and x = 5

• x = 2 and x = 3

• x = -2 and x = -3

• x = 2 and x = -3

• x = -2 and x = 3

• -2, 4
• -8
• ±8
• No real solution

Find the zeros of this quadratic.

• b=4/5, b=3

• b=4, b=-3

• b=1/5, b=3

• b=4/5, b=-3

Solve
a² + 2a - 24 = 0

• a = -6, 4

• a = 6, -4

• a = 12, -2

• a = 8, -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
