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

What is the discriminant?

• b² - 4ac

• b² / 2a

• 4ac

• b² ± 4ac

If the discriminant equals 0, then the quadratic has:

• 1 Real Solution

• 2 Real Solutions

• Half a Solution

• No Real Solution

If the discriminant is negative, then the quadratic has:

• 1 Real Solution

• 2 Real Solutions

• Half a Solution

• No Real Solutions
