Find roots of quadratic equation using discriminant - Precalculus

WebExplanation: . This is true. The discriminant b 2 - 4ac is the part of the quadratic formula that lives inside of a square root function. As you plug in the constants a, b, and c into b 2 - 4ac and evaluate, three cases can happen:. b 2 - 4ac > 0. b 2 - 4ac = 0. b 2 - 4ac < 0.
