Determine the values of

a, b, and c for

the quadratic equation:

4x² – 8x - 3 = 0

• a = 4, b = -8, c = 3

• a = 4, b =-8, c =-3

• a = 4, b = 8, c = 3

• a = 4, b = 8, c = -3

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

• 16
• -8
• 8
• -24

For the following quadratic equation, what is the value of c ?

5x² + 7x - 11 = 0

• 5

• 7

• 11

• -11

For the following quadratic equation, what is the value of a ?

x² - 7x + 2 = 15

• 0

• x²

• -7

• 1

Use the quadratic formula to find the solutions for

-x² - 5x + 12 = 0

• -4.9 and -0.1

• -8.54 and 8.54

• -0.45 and 3.55

• -6.77 and 1.77

Solve by factoring:  4x² + 11x - 3 = 0

• x = -3/4 and x = -1
• x = 4 and x = 3
• x = 1/4 and x = -3
• x = -1/4 and x = 3
