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
