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

If the discriminant is positive, then the equation will have...

• one real solution

• two real solutions

• no real solutions

• one imaginary solution
