Web21 aug. 2024 · What do you do when the discriminant is 0? If the discriminant is equal to zero, this means that the quadratic equation has two real, identical roots. Therefore, there are two real, identical roots to the quadratic equation x2 + 2x + 1. D > 0 means two real, distinct roots. What if the discriminant is less than zero? 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. In the first case, having a positive number under a square root function will yield a result that is …
