quadratic, mathematical expression of the second degree in one or more unknowns (see polynomial polynomial, mathematical expression which is a finite sum, each term being a constant times a product of one or more variables raised to powers. With only one variable the general form of a polynomial is a₀xⁿ+a

A quadratic equation ax²+bx+c=0 always has two roots root, in mathematics, number or quantity r for which an equation f(r)=0 holds true, where f is some function . If f is a polynomial , r is called a root of f; for example, r=3 and r

The expression b²−4ac is called the discriminant and vanishes when the two roots coincide. If a, b, and c are real and the discriminant is not less than zero, the roots are real.
