Answer:
To multiply two binomial use the FOIL method. F stands for first. O stands for outside. I stands for inside. L stands for last. So you first multiply the first numbers or variables of the binomials. Then you use the first variable in the fist binomial but multiply the last term in the second binomial. Next use the second term in the first binomial and multiply it with the first term in the second binomial. Last use the last two terms in both binomials and multiply them. THen finally simplify like terms.
