Answer:

top of fraction: -2(n^8+2)(n^3+8n+2)

bottom of fraction: n^5

Explanation:

use PEMDAS for the first part of the equation, then for the other half multiply it by -1, then pull them back into the equation and solve, and you should get the answer above the way i did it, if not then hope you find another person who is correct, remember i'm a student as well i'm not perfect

Answer:


n^(3)+4n^(2)-8n-9

Explanation:

The only thing that you have to do is to add the different terms that have the same exponent and the same algebraic term.


2n^(3) -n^(3)=
n^(3)


4n^(2)

-8n

-7 -2= -9

After adding up the different terms:


n^(3)+4n^(2)-8n-9
