In elementary algebra, aquadratic equation (from the Latinquadratus for "square") is any equation having the form

wherex represents an unknown, anda, b, andc represent known numbers such thata is not equal to 0. Ifa = 0, then the equation is linear, not quadratic. The numbersa, b, andc are thecoefficients of the equation, and may be distinguished by calling them, respectively, thequadratic coefficient, thelinear coefficient and theconstant orfree term.
Because the quadratic equation involves only one unknown, it is called "univariate". The quadratic equation only contains powers ofx that are non-negative integers, and therefore it is a polynomial equation, and in particular it is a second degree polynomial equation since the greatest power is two.
