What is the discriminant of the quadratic equation 0 = –x^2 4x – 2? a. –4 b. 8 c. 12 d. 24

If you would like to know the discriminant of the quadratic equation 0 = -x^2 + 4x - 2, you can do this using the following steps:

0 = -x^2 + 4x - 2

0 = ax^2 + bx + c
a = -1, b = 4, c = -2

D = b^2 - 4 * a * c = 4^2 - 4 * (-1) * (-2) = 16 - 4 * 2 = 16 - 8 = 8

The correct result would be b. 8.
