About the Discriminant Calculator
The discriminant of a quadratic equation ax² + bx + c = 0 reveals the nature of its roots without solving for them fully.
Formula: Discriminant = b² − 4ac
A positive discriminant means two distinct real roots, zero means one repeated real root, and a negative discriminant means two complex roots.
