Answer:

$9n^2 - 5n$

Step-by-step explanation:

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

Lets open the brackets. Signs of all the terms in the bracket next to the minus sign will change.

$=> 3n^3 - 5n + n^2 + 8n^2 - 3n^3$

Now lets add/substract all the like terms with each other.

$=> 3n^3 - 3n^3 + n^2 + 8n^2 - 5n$

$=> 9n^2 - 5n \: \: or \:\: n(9n - 5)$
