Solve a Quadratic Equation by Factoring

This page will try to solve a quadratic equation by factoring it first. How does this work?

Well, suppose you have a quadratic equation that can be factored, like

x²+5x+6=0. This can be factored into (x+2)(x+3)=0.

So the solutions must be x=-2 and x=-3.

Note that if your quadratic equation cannot be factored, then this method will not work.
