ANSWER

EXPLANATION
The first polynomial is

The second polynomial is

If we add the two polynomials we obtain,

Next we group like terms to obtain,

We simplify the to obtain,

This is the sum of the two polynomials in descending powers of

Descending means from the highest power to the least.
So it went from 30 to 35, or 5 bucks, if we take 30 to be the 100%, what is 5 off of it in percentage?
