17x^9+10x^6+7x+13

Explanation:

First of all, when you are adding polynamials, you have to add the like terms. For example you can add 2x and 4x but not 4x^2

Since there is no negative or minus sign, you can remove the brackets.

Combine the terms that are similar
8x^9+9x^9+6x^6+4x^6-2x+9x+6+7

Therefore combining like terms, you get
17x^9+10x^6+7x+13
