Question

Which two values of x are roots of the polynomial below?

Answer 1

Answers: choice A, choice C

Compute the discriminant (use a = 1, b = 5, c = 11)

D = b^2 - 4ac

D = 5^2 - 4*1*11

D = 25 - 44

D = -19

The discriminant is negative, so the two solutions are complex or imaginary. The -19 will be under the root as choice A and choice C show
