To solve a quadratic equation, the first thing you need to do is write it in standard form, meaning the exponents are going in decreasing order and it is equal to zero. From there, look for a greatest common factor. Factor what is left. Then set each factor equal to zero because of the zero product property, and solve each one for x. It is always a good idea to check your work by substituting each value back into the original equation to make sure it is indeed a solution.
