If the discriminant of a quadratic equation is equal to -8, which statement describes the roots? a. there are two complex roots. b. there are two real roots. c. there is one real root. d. there is one complex root.

Type the correct answer in the box. consider the system of linear equations below. rewrite one of the two equations above in the form ax + by = c, where a, b, and c are constants, so that the sum of the new equation and the unchanged equation from the original system results in an equation in one variable.
