------------------------------
I don't know what subtraction you mean, unless it's the minus sign in (a-b). If that's it, it means the signs of the terms alternate + and - in the expansion.

%28a-b%29%5E6=a%5E6-6a%5E5b%2B15a%5E4b%5E2-20a%5E3b%5E3%2B15a%5E2b%5E4-6ab%5E5%2Bb%5E6
That's what it is, using Pascal's triangle.
If that's not sufficient, just repost it.
