Question: This is multiplying a polynomial and its quite confusing for me (5-4n+4n^4)-(3+3n^4)+(8+2n^3+8n) P.S. the "^" is the exponent sign

Well, there are no products or parenthetical exponents to worry about, so go ahead and get rid of the parentheses. Remember that when you are subtracting a term within parentheses, you are subtracting the whole thing, so change the sign of everything within. It would become 5-4n+4n^4-3-3n^4+8+2n^3+8n. Isolate like terms. 5-3+8+8n-4n+4n^4-3n^4+2n^3. Then combine. 10+4n+n^4+2n^3. Your teacher will probably want you to put it in greatest to least form, so put it like this, n^4+2n^3+4n+10.
