For a complete lesson on multiplying polynomials, go to http://www.MathHelp.com - 1000+ online math lessons featuring a personal math teacher inside every lesson! In this lesson, students learn to multiply a binomial times a trinomial, such as (r -- 7)(r^2 + 6r + 2), by distributing each of the terms in the binomial through the trinomial, then combing like terms. Students also learn to simplify a binomial cubed, such as (3c -- 2)^3, by rewriting the problem as (3c -- 2)(3c -- 2)(3c -- 2), FOILing the first two binomials together, then multiplying the resulting trinomial times the last binomial, and combining like terms.
