In algebra, a quadratic equation (from the latin quadratus for square) is any equation having the form -ac + + = where x represents an unknown, and a, b, and c represent known numbers such that a is not equal to 0if a = 0, then the equation is linear, not quadraticthe numbers a, b, and c are the coefficients of the equation, and may be distinguished by calling them, respectively, the.
