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

Use the quadratic formula to solve 2x² + 2x - 12 = 0

• x = { -2, 3 }

• x = { 2, 3 }

• x = { 2, -3 }

• x = { -2, -3 }
