This document provides steps for multiplying a binomial and a trinomial. It instructs the user to draw a table, fill in the terms, write the polynomials from greatest to least exponent, and combine like terms. The result of multiplying (7z^3 + 6z^2 + 3z) and (4z^3 + 1z) is 28z^6 + 24z^5 + 19z^4 + 6z^3 + 3z^2.
