This document provides instructions for multiplying a binomial and a trinomial. It explains that you must make a multiplication box, multiply the coefficients and add the exponents. You then put the terms in descending order by exponent and combine like terms by adding them. The final answer to the sample equation (30x^6 + 8x^2 + 10)(15x^3 + 21) is 576x^16 + 120x^5 + 150x^3 + 168x^2 + 210.
