First, write the term that has the largest exponent for 'x'. That would be -2x%5E3. Now add on the next term that has the second largest exponent for 'x'. That would be 3x%5E2y.

So far, we have -2x%5E3%2B3x%5E2y. Now add on the next term has the third largest exponent for 'x', which is 5xy%5E2 to get -2x%5E3%2B3x%5E2y%2B5xy%5E2. Now finally add on the last term -9 to get -2x%5E3%2B3x%5E2y%2B5xy%5E2-9

So the answer is -2x%5E3%2B3x%5E2y%2B5xy%5E2-9

Write each polynomial in descending order of the variable x.

5xy%5E2%2B3x%5E2y-9-2x%5E3=-2x%5E3%2B3x%5E2y%2B5xy%5E2

where I started with the highest number in the exponent of "x" and work my way down.

I hope the above steps and explanation were helpful.
