Question

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

O There are two complex roots.
O There are two real roots.
O There is one real root.
O There is one complex root.

Answer 1

would be A. There are two complex roots

Explanation:

Answer 2

There are two real roots

Explanation:

From the value of the discriminant b² - 4ac

• If b² - 4ac > 0 then 2 real and distinct roots

• If b² - 4ac = 0 then 2 real and equal roots

• If b² - 4ac < 0 then 2 complex roots

Here b² - 4ac = 8 > 0 , then there are two real roots
