Discriminant

A discriminant is a quantity (usually invariant under certain classes of transformations) which characterizes certainproperties of a quantity's Roots. The concept of the discriminant is used forBinary Quadratic Forms, Elliptic Curves, Metrics, Modules, Polynomials, Quadratic Curves, Quadratic Fields, Quadratic Forms, and in the Second Derivative Test.
