The polynomial is complete, starting from the highest power to the lowest, covering all the terms.

Step-by-step explanation:

To write the complete polynomial in descending order, we will first rearrange the expression starting with the term which has the highest power and then add the missing terms in it using 0 as the coefficient for x:

Now add the missing terms to get the complete polynomial in a descending order:
