It turns out that the solutions to any quadratic will form the factors of the quadratic itself. So let's say that we want to factor . We know that this factors to . But if we didn't know that, we can use the quadratic formula to find the solutions and . From there, we need to get all terms to one side to get and . Now just combine the two equations into one like this (note: this is using the zero product property in reverse).
