Determine the values of
a, b, and c for
the quadratic equation: 
4x² – 8x = 3
*remember right side should =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

Solve by using the quadratic formula.

7x² - 26x - 8 = 0

• x = -1 and x = -7/8

• x = 4 and x = -2/7

• x = -4 and x = 2/7

• x = 4 and x = -7/2

Solve for x. Round to the nearest hundredth if necessary.

3x² = 16x + 12

• x = -0.67 and x = 6

• x = -6 and x = 0.67

• x = 3.33 and x = 18

• x = -3.33 and x = 18
