Show All Steps Hide All Steps. Be careful when the coefficient of the squared term is not a one. And thats very important then the solution to any quadratic equation is x b b2 4ac 2a x b b 2 4 a c 2 a.
Note however that it is okay if b andor c are zero.
Unfortunately the answer is it depends. In algebra a quadratic equation is any polynomial equation of the second degree with the following form. First the standard form of a quadratic equation is ax2 bxca00 The only requirement here is that we have an x2 in the equation. The standard form of a quadratic equation is.
