Answer:

[tex]n^{3}+4n^{2}-8n-9[/tex]

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.

[tex]2n^{3} -n^{3}[/tex]= [tex]n^{3}[/tex]

[tex]4n^{2}[/tex]

-8n

-7 -2= -9

After adding up the different terms:

[tex]n^{3}+4n^{2}-8n-9[/tex]
