Determine the values of a, b, and c for the quadratic equation:

4x² – 8x = 3

*Reminder: the equation MUST equal zero.

• a = 4, b = -8, c = 3

• a = 4, b =-8, c =-3

• a = 4, b = 8, c = 3

• a = 4, b = 8, c = -3

In the equation x²+4=0, match each leading coefficient with its correct letter. 

• a=0 b=4 c=0
• a=1 b=4 c=0
• a=1 b=0 c=4
