Question 984700
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.


Know that when you perform regular multidigit long multiplication for power-of-ten regular numbers, you are essentially doing something like a lattice method.  The often included act of "carrying" condenses the process and hides the lattice characteristic about the method from the student (or whoever is doing the multiplication).
