## The correct answer is: Hence, we use the identity to find the product of the expression.

### ANSWER:

Hint:

, where x and a can be real values, variables or multiples of both.

We are asked to use identities to multiply the given expression.

Step 1 of 2:

The given expression is . Hence, we use the identity to find the product of the expression

Note:

We use identities to speed up the process of multiplication and simplification. There are some basic polynomial identities that you need to by heart.
