Quadratic equation
A quadratic equation (from the Latin quadratus for “square“) is any equation that can be rearranged in standard form as: \[ax^2+bx+c=0\] where \(x\) represents an unknown, and \(a\), \(b\), and \(c\) represent known numbers, where \(a\neq 0\). If \(a=0\), then the equation is linear, not quadratic, as there is no \(ax^2\) term. The numbers \(a\), \(b\), and […]
