The discriminant is the part of the quadratic formula under the radical sign: $b^2-4ac$. The discriminant determines the number of solutions in a given equation. For instance, if: $b^2-4ac = 0$, then there is one real number solution. $b^2-4ac =$ $negative$ $number$, then there are two imaginary solutions. $b^2-4ac =$ $positive$ $number$, then there are two real number solutions.
