Question

what is the value of the discriminant of the quadratic equation −2x2 = −8x 8, and what does its value mean about the number of real number solutions the equation has?

Answer 1

A. The discriminant is equal to 0, which means the equation has no real number solutions.

Explanation:

Answer 2

`2x^2-8x+8=0 \\ d= b^(2) -4ac \\ =(-8)^2-4 * 2 * 8 \\ =64-64 \\ =0`
Since the discriminant is 0, the equation has one real number solution.
