Quadratic Function Notation

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

• x = 2 and x = 3

• x = -2 and x = -3

• x = 2 and x = -3

• x = -2 and x = 3
