Grav, are you sure you know how? It doesn't look like it. Here's a trick I learned in middle school. It's called FOIL. FOIL stands for "First Outside Inside Last." It means you take the sum of the products of the first term in each binomial, the product of the first term of the first binomial and the last of the second(the outside ones), the product of the last term of the first binomial and the first of the second(the inside ones), and the product of the last term in both binomials.
(a+b)(c+d)=ac+ad+bc+bd
