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

Identify the 'b' value:
0 = -24 - 8x +16x²

• 16

• -8

• 8

• -24

In the equation ax²+bx+c=0, the c term is always the... 

• x² term

• x term

• constant

• zero

Identify the 'a' value:
16x² = -8x -24

• 16

• 8

• -8

• -24
