The Discriminant - KATE'S MATH LESSONS
We can use the Quadratic Formula to solve quadratic equations if we want the exact answers. The discriminant is just part of the Quadratic Formula and can tell us quite a bit about a quadratic equation. The discriminant is the number we end up with under the square root in the Quadratic Formula: the b squared minus 4ac part.[PDF]
