ax²+bx+c=0  is the standard form of a quadratic equation.

• True

• False

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

• A.

  a = 4, b = -8, c = 3

• B.

  a = 4, b =-8, c =-3

• C.

  a = 4, b = 8, c = 3

• D.

  a = 4, b = 8, c = -3

What value of c would make this a perfect sqaure trinomial?
x² +8x + c

• A. 4

• B. 16

• C. 64

• D. - 16
