Question

What is `(8x^9+6x^6-2x+6)+(9x^9+4x^6+9x+7)`?

Answer 1

`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`
