The document provides an explanation of how to use the FOIL method to multiply binomial expressions. It defines what a binomial is, explains that FOIL is a mnemonic for the steps of First, Outer, Inner, Last. It then demonstrates how to use FOIL by working through simple examples without variables and a more complex example with variables, showing the pairing and multiplication of terms according to the FOIL steps. Additional resources on FOIL multiplication are provided.
