# How do you find the sum or difference of #(3n^3-5n+n^2)-(-8n^2+3n^3)#?

See the entire solution process below:

First, remove all of the terms from parenthesis. Be careful to handle the signs of each individual term correctly:

Next, group like terms:

Now, combine like terms:

To find the sum or difference of ((3n^3 - 5n + n^2) - (-8n^2 + 3n^3)), first remove the parentheses and then combine like terms:

(3n^3 - 5n + n^2 + 8n^2 - 3n^3)

Combine like terms:

(3n^3 - 3n^3 + 8n^2 + n^2 - 5n)

(0n^3 + 9n^2 - 5n)

So, the sum or difference is (9n^2 - 5n).
