Discriminant Definition

A discriminant is a function of the coefficients of a polynomial equation that expresses the nature of the roots of the given quadratic equation. The equations can discriminate between the possible types of answer, such as:

When the discriminant value is positive, we get two real solutions
When the discriminant value is zero, we get one real solution
When the discriminant value is negative, we get a pair of complex solutions
