- Quadratic equation - Wikipedia
In mathematics, a quadratic equation (from Latin quadratus ' square ') is an equation that can be rearranged in standard form as [1] + + =, where the variable x represents an unknown number, and a, b, and c represent known numbers, where a ≠ 0 (If a = 0 and b ≠ 0 then the equation is linear, not quadratic )
