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
*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

• No real solutions
