Note that this trinomial does have a GCF of 2y. It is of the form.
Multiplying Binomials Using the Foil Method Multiplying polynomials becomes a little trickier when you multiply two binomials. We are still going to use the distributive property, but many students refer to the acronym, FOIL in order to remember the steps for multiplying binomials.
I am actually going to show you two ways to multiply binomials. The first way is thinking of it as another way to use the distributive property. Let's take a look at the following examples.
Using the Distributive Property We will use the distributive property to multiply the following binomials: That is the process for multiplying binomials, but eventually you'll be able to complete this process without writing out each step of the distributive property.
I wrote it out, in hopes that you will understand the process. You will be able to do a lot of those steps mentally!
One way to help you remember the steps to perform mentally is to remember the acronym, FOIL. If you compare each step in the first example, to the steps used in example 2 with the foil method, you will find that they are pretty much the same. Let's take a look! Let's see how we can use FOIL to multiply two binomials.
Using Foil Let's take a look at the same problem demonstrated in Example 1 and see how FOIL can help us to remember all the steps in multiplying binomials.
We will multiply the same two binomials: So, you can think of it as distributing one binomial throughout the other or you can remember FOIL to perform the same steps!
Let's look at another example using FOIL. It only works when you are multiplying two binomials. This is not the only method used when multiplying polynomials and it doesn't work for all polynomials. It ONLY works with two binomials! Are you ready to practice?

May 16, · Okay so I am in the 8th grade and I missed the lesson over the FOIL method, so my teacher told me to get on the Internet and find out what it means and work out this work sheet she gave me.
Practice with a few math problems, and you'll get the hang of it! (: Mary Magdalene. You mad!? · 8 years ago. 1. Thumbs up. 0. Thumbs down Status: Resolved. How do you FOIL a math problem witha binomial and a trinomial?
FOIL is an acronym standing for first, outside, inside, and last, which is a method for multiplying binomials. For example.
