WebWolfram Alpha can apply the quadratic formula to solve equations coercible into the form ax2 +bx+c= 0 a x 2 + b x + c = 0. In doing so, Wolfram Alpha finds both the real and complex roots of these equations. It can also utilize other methods helpful to solving quadratic equations, such as completing the square, factoring and graphing. WebThere are two distinct mechanisms used to specify which root of an equation is represented, the neighborhood representation Root [{f, c}] and the indexing representation Root [f, k]. The root neighborhood representation Root [ { f , c } ] specifies the equation f [ x ] 0 as well as the neighborhood rectangle centered at c and width and height .
