Quadratic Formula

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 =3

• a=-4 b=-8 c=-3

• a=4 b=-8 c=-3

• a = 2 , b = 3, c = -5

• a = 2, b = -3, c = 5

• a = 2, b = -3, c = -5

• a = -2, b = 3, c = 5

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

• -2, 3
• 2, 3
• 2, -3
• -2, -3

Solve using the quadratic formula.
2x² - 9x - 35 = 0

• x = 7/2, x = -6
• x = -5/2, x =5
• x = -3/7, x =6
• x = -5/2, x = 7
