In algebra, a quadratic equation (from the Latin quadratus for "square") is any equation having the form
ax^{2}+bx+c=0
where x represents an unknown, and a, b, and c represent known numbers such that a is not equal to 0. If a = 0, then the equation is linear, not quadratic. The numbers a, b, and c are the coefficients of the equation, and may be distinguished by calling them, respectively, the quadratic coefficient, the linear coefficient and the constant or free term.

x^{2}x
