Frequently asked questions
What does it mean if the roots are complex numbers?
It means the equation has no real solutions, which happens when the discriminant, the value under the square root in the quadratic formula, is negative.
What is the discriminant used for?
It determines the nature of the roots, showing whether the equation has two distinct real roots, one repeated real root, or a pair of complex roots.
