### Example Question #61 : Variables

Rewrite the polynomial in standard form:

**Possible Answers:**

**Correct answer:**

The degree of a term of a polynomial with one variable is the exponent of that variable. The terms of a polynomial in standard form are written in descending order of degree. Therefore, we rearrange the terms by their exponent, from 5 down to 0, noting that we can rewrite the and constant terms with exponents 1 and 0, respectively:
