    • A discriminant is a quantity (usually invariant under certain classes of transformations) which characterizes certain properties of a quantity's roots. The concept of the discriminant is used for binary quadratic forms, elliptic curves, metrics, modules, polynomials, quadratic curves, quadratic fields, quadratic forms, and in the second derivative test.
