Foil and find the product combine like terms

Solution

Let\'s look at the second binomial which is (3x + x + 3). Notice that there are two x\'s. You can combine them because they both have x. This is the key of combining like terms.

For instance, you have a problem such as: 3x + y. You cannot add both because both have different variables. Now back to the problem. 3x + x = 4x. Now, rewrite the problem which is: (4x + 3)

Now, the entire problem is: (3x + 5)(4x + 3).

Now, go ahead and use the FOIL method. You may ask what is the FOIL method? The key to understanding this method is to understand what each letter in the word \'FOIL\' means.
