Quadratic Formula Review

What are a, b, and c in the quadratic?

• a = -5, b = 3, c = -10

• a = 5, b = 3, c = -10

• a = 5, b = -3, c = 10

• a = 5x², b = -3x, c = 10

Identify the 'a' value: y = 16x² -8x -24

• 16
• 8
• -8
• -24

Determine the values of

a, b, and c for

the quadratic equation:

4x² – 8x = 3

(Get 0 on one side first!)

• a = 4, b = -8, c = 3

• a = 4, b =-8, c =-3

• a = 4, b = 8, c = 3

• a = 4, b = 8, c = -3
