Solving by factoring

The quadratic formula will give you solutions for any quadratic equation, but it may require complicated calculations. Sometimes there’s no way around that. Completing the square is complicated, the quadratic formula can be complicated, and irrational solutions aren’t easy. In other cases, however, the quadratic polynomial can be factored and the equation can be solved by applying the zero product property. If the product of two factors is 0, then at least one of the factors is 0. If the quadratic can be factored, that’s probably the easiest way to solve.

First, put the equation in standard form. With all terms on one side of the equation equal to 0, factor the quadratic expression. Set each factor equal to 0 and solve the resulting equations.
