do things just as you would with numbers:
(2+5)(73)
2*7 + 5*7  2*3  5*3
You have
(n^3+8)(n4)
n^3*n + 8*n  n^3*4  8*4
now simplify each term
n^4 + 8n  4n^3  32
and arrange in descending powers
n^4  4n^3 + 8n  32
Sometimes you may have several terms with the same power. In that case, collect them into a single term. For example,
n^3  2n^2 + 3 + 9n^2  2n + 3  4n
would become simply
n^3 + 7n^2  6n + 6
