Multiplying Polynomials To multiply polynomials, multiply each and every term in the first polynomial by each and every term of the second polynomial. Combine like terms.

The process for multiplying binomials remains the same. You multiply each term of the first binomial with each term of the second binomial. There is a nifty pneumonic to help you remember the procedure.

Multiply each and every term in the first polynomial by each and every term of the second polynomial.
