These are just a few popular acronyms that you may know. There is one thing that you need to remember with FOIL! I - Inner terms. One of the biggest drawbacks of using the FOIL method is that it can only be used for multiplying two binomials. So First says just multiply the first terms in each of these binomials. Here are some more examples of FOIL multiplication: Example: Multiply the following: $$(6x+1)(2x+9)$$ Solution: Just follow the letters in FOIL: First: $$6x*2x=12x^2$$ Outside: $$6x*9=54x$$. In other words, using the previous example: Use foil to simplify (x + 3)(x + 2) In the next lesson, we will take a look at a few "special cases" when multiplying binomials! the quantity (2x + 1).
