How do you combine like terms in #(7+ 4x + 9x ^ { 2} + 2x ^ { 3} ) + ( 3- 4x + 9x ^ { 2} - 2x ^ { 3} )#?

Explanation:
To combine like terms you need to add terms which have exactly the same variables together.
Remove the brackets first. We cab just leave them out because a plus sign in front does not change the terms inside the bracket at all.
Re-arrange the terms with the like terms together.
Simplify: The terms do not change, only the numbers change.
