When a quadratic equation becomes an identity?

A quadratic equation becomes an identity (a, b, c = 0) if the equation is satisfied by more than two numbers, i.e. having more than two roots or solutions either real or complex. The values of variables satisfying the given quadratic equation are called their roots. In other words, x = ? is a root of the quadratic equation f (x), if f (?) = 0.
