I have a considerably long formula involving binomial coefficients. I wish to tell Mathematica to give a (symbolic) representation of these binomial coefficients, but I don't know how. For example in
..(-2 + n)(-1 + n)*A + (-2 + n)(-1 + n)(-3 + n)*B..
I would like to get
.. 2*Binomial(n,2)/n*A + 6*Binomial(n,3)/n*B...
How can I do that?
I appreciate your help!
PS: Why don't you add latex notation in the forum?
