Question

Find the sum 2n^3 +4n^2-7 and -n^3-8n-2

Answer 1

Answer:

$n^{3}+4n^{2}-8n-9$

Step-by-step 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:

$n^{3}+4n^{2}-8n-9$

Answer 2

Answer:

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

bottom of fraction: n^5

Step-by-step 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
