In %28-5%2B6x%5E7%2B2x%5E5%29+%2B+%289x%5E7%2B5x%5E5%2B9%29 you will need to add "like terms", that is, terms where the exponent is the same. You have two terms with exponent of 7, two terms with exponent 5 and two terms with no exponent.
Rearranging so that we have "like terms" together, we get:
6x%5E7+%2B+9x%5E7+%2B+2x%5E5+%2B+5x%5E5+-+5+%2B+9
Combining "like terms" gives us the answer:
15x%5E7+%2B+7x%5E5+%2B+4
