Question

If the discriminant of a quadratic equation is equal to -8, which statement describes the roots?

There is one real root.

There are two complex imaginary roots.

There is one complex imaginary root.

There are two real roots.

Answer 1

Explanation:

A discriminate of -8 is never going to give you a real root. D is wrong

You cannot have just 1 complex root, nor can you have just 1 real root unless the discriminate is 0. A and C are both wrong for the same reason. 1 complex root is impossible. They come in pairs.

So the answer is B. You have 2 complex roots.
