Question

What is the value of the discriminant of the quadratic equation -2x^2=-8x+8, and what does its value mean about the number of real number solutions the equation has?

Answer 1

`- 2 {x}^(2) = - 8x + 8 \\ - 2 {x}^(2) + 8x - 8 = 0`
Discriminant:

`{b}^(2) - 4ac \\ = {8}^(2) - 4( - 2)( - 8) \\ = 64 - 64 = 0`
If the discriminant = 0, it is double real roots.
If the discriminant > 0, it is real roots.
If the discriminant < 0, there are no real roots.
