find the following product
7z (3z^3  2z+ 4)

7z (3z^32z+4)= 21z^414z^2+28z i could show you much better vertically, but i can'tmake the curser go where i want nor can i print the numbers on the line that i want, but you simply mult each factor in each term, in this case one term, by each factor in every other term one time only.
