Distributive Property should be used for the polynomial products, but once that is learned
then use of a lattice approach will often be more comfortable to get each partial product term.
Here will use the Distributive Property to start.

Some people can combine like-terms in their head as they go, and some cannot...

Check to be sure that the same count of terms is there as in the previous step before actually
combining those like-terms.
