I seem to be mentioning gino a lot lately - symbolic questions are
becoming popular on the list. If you install gino[1], you can expand the
expression in a slightly less cumbersome manner because it works with
Octave strings rather than trying to interpret expressions:

octave> g_expand ('(x-1)^3')
ans = -1+3*x+x^3-3*x^2
