### Example Question #1 : Polynomials

Multiply the following polynomials:

**Possible Answers:**

**Correct answer:**

Multiply the following polynomials:

When multiplying polynomials, we need to multiply each term in the first polynomial by each term in the second polynomial.

We can rewrite the expression as:

Next, actually do the multiplication.

Finally, combine like terms to get the following:

### Example Question #2 : Polynomials

Identify the power of the following polynomial

**Possible Answers:**

**Correct answer:**

To find the power of a polynomial, you must find the term with the highest degree. Don't be fooled, you must distribute the power on the outside to the inside in order to find this term. Now, before you start worrying about foiling this 4 times, you can simply use the trick of distributing the outside power to the term on the inside with the largest power. Thus, our answer is:
