Question

Find the discriminant and describe the roots for this equation x^2+3x+8=0

Answer 1

Explanation:

The discriminant of a quadratic equation is b² - 4ac.

Here, a = 1, b = 3 and c = 8, and so the value of the discriminant is:

3² - 4(1)(8) = 9 - 32 = -23

The discriminant is -23 in this case.

A negative discriminant indicates that the roots will be complex.
