Hey there!
To solve this problem, we will take a look at the FOIL Method.
<h3>What is "FOIL"?</h3>FOIL is a simple acronym that can be used to multiply binomials. It stands for:
F - Front
O - Outer
I - Inner
L - Last
See the image below for an example of how to use this in the given situation.
<h3>Apply</h3>Front: <em>Multiply the two terms out in the front.</em>
Outer: <em>Multiply the two terms on the outsides.</em>
Inner: <em>Multiply the two terms on the insides.</em>
Last: <em>Multiply the two terms in the back.</em>
Now, we add all of our answers from above:
Simplify by combining like terms:
There's our answer!
