Question

Quizplus · Accepted Answer

This is true. The discriminant is used to determine the nature of the solutions (real, imaginary, or repeated) of a quadratic equation. If the discriminant is positive, there are two distinct real solutions. If it is zero, there is one repeated real solution. If it is negative, there are two complex conjugate solutions.
