Answer:

-13n^4 + 11n^3 - 3n^2 - 3

Step-by-step explanation:

*I think you mistyped the question. I belive the 13n^4 is supposed to be negative*


1.First, we need to add common values (all the n^4s together, all the n^3s, etc.) from the two sets.

-13n^4

12n^3 + -n^3

8n^2 + -11n^2

-3

2. Now lets simplify

-13n^4

11n^3

-3n^2

-3

3. Laststly, we put them all into one expression!

-13n^4 + 11n^3 - 3n^2 - 3
