FOIL using the distributive property.

Simplify. 

To FOIL this binomial distribution, we simply distribute the terms in a specific order:

Multiply the First terms:

Multiply the Outer terms:

Multiply the Inner terms:

Multiply the Last terms:

Lastly, combine any terms that allow this (usually, but not always, the two middle terms):

Arrange your answer in descending exponential form, and you're done.

Notice that this answer is also a difference of squares.

The trick to this expression is to remember that only those terms which share both common variables AND common exponents are additive. In other words, you cannot add  any more than you can add .

To FOIL this binomial distribution, we simply distribute the terms in a specific order:

Multiply the First terms:

Multiply the Outer terms:

Multiply the Inner terms:

Multiply the Last terms:

Lastly, combine any terms that allow this (usually, but not always, the two middle terms). In this case, no two terms are compatible.

Arrange your answer in descending exponential form, and you're done.

Use the grid method to FOIL.

Combine the like terms.

Using FOIL which stands for the multiplication process between the Firsts, Outers, Inners, and Lasts, we end up with the expression 

.

From there, combine the like terms  to get .

Therefore the product becomes,
