# Do you multiply when foiling?

## Do you multiply when foiling?

You don’t have to multiply binomials by following the FOIL order, but it does make the process easier. The letters in FOIL refer to two terms (one from each of two binomials) multiplied together in a certain order: First, Outer, Inner, and Last. Multiply the inner terms together.

## Why cant the foil method be used to multiply all polynomials?

Unfortunately, foil tends to be taught in earlier algebra courses as “the” way to multiply all polynomials, which is clearly not true. (As soon as either one of the polynomials has more than a “first” and “last” term in its parentheses, you’re hosed if you try to use Ffoil, because those terms won’t “fit”.)

Where can foil method be used?

You can use FOIL to multiply three or more binomials if you pair them off, then factor the answer to the remaining binomial. FOIL cannot be used for binomial addition, subtraction, or division.

### When should I use FOIL method?

You use the FOIL method when you are multiplying two binomials; that is multiplying two factors with two terms in each factor.

### When can you not use FOIL in math?

If students want to use FOIL, they need to be forewarned: You can ONLY use it for the specific case of multiplying two binomials. You can NOT use it at ANY other time! to vertical multiplication, because it is much easier to use, but there is another way. It is called the clam method.

How do you do foil in math?

The letters FOIL stand for First, Outer, Inner, Last. First means multiply the terms which occur first in each binomial. Then Outer means multiply the outermost terms in the product.”

#### How do you multiply Binomials using foil?

Use the FOIL method for multiplying two binomials

1. Multiply the First terms.
2. Multiply the Outer terms.
3. Multiply the Inner terms.
4. Multiply the Last terms.
5. Combine like terms, when possible.

#### What is FOIL in quadratic equation?

When we multiply (x−3) times (x−4) to obtain x2−7x+12 x 2 − 7 x + 12 we call that operation “multiplying out” or sometimes FOILing. (Recall that FOIL stands for First, Outer, Inner, Last, which is how we combine the terms.)
