• -3

Determine the values of

a, b, and c for

the quadratic equation:

4x² – 3x = 5x + 3

(EQUATION MUST EQUAL ZERO)

• a = 4, b = -8, c = 3

• a = 4, b =-8, c =-3

• a = 4, b = 8, c = 3

• a = 4, b = 8, c = -3

Determine the values of

a, b, and c for

the quadratic equation:

2x² + x = -3x - 5

(EQUATION MUST EQUAL ZERO)

• a = 2, b = -2, c = 5

• a = 2, b =-3, c =-5
