To solve a quadratic equation by factoring, it first has to e equal to zero, which we call standard form. Start by multiplying out any products (like distributing of FOILing), and then move all terms to the same side of the equal sign. Rewrite it so that the exponents go in decreasing order. Then factor, and use the zero product property to find your final solutions. Since there are so many steps and so many places to make errors, be sure to check your final solutions by substituting each one in one at a time to the original equation.
