This is a worksheet that I put together to help students with multiplying polynomials. It goes over multiplying a monomial by a monomial, a monomial by a binomial, binomial with a binomial (FOIL and Box methods used here), and multiplying a binomial with a trinomial (used distributive method and box method). Some exercises are provided to give students a chance to apply what they learn.
I tagged this as not grade specific. I teach at a community college, so I do not know which grade levels to apply.
