Use distributive property and combine like-terms if any occur. If your polynomial factors have more than two terms each, then a lattice type form of multiplication would make the work easier, and more organized. This way, you simply fill-in cells, and then identify the like-terms and combine, ... but you can still use distributive property; it is just more difficult to use if the factors are too many terms.\r
