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

Solve the following quadratic equation...

x² + 3x + 2 = 0

• x = -1

  x = -2

• x = 1

  x = 2

• x = -1

  x = 2

• x = 1

  x = -2
