**Steve**, Wednesday, June 25, 2014 at 5:51amdo things just as you would with numbers:

(2+5)(7-3)

2*7 + 5*7 - 2*3 - 5*3

You have

(n^3+8)(n-4)

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
