[net.math] need help with series summation

cab@allegra.UUCP (Carol Beck) (10/09/84)

If you're looking for an exciting, stimulating problem, the solution
of which reveals the inner harmony of the universe,
		THIS IS NOT IT.
You have been warned.

{the sum from a=0 to n of:}
		((a+b)C(d-a))*P**(2*a)
where qCr is
		q!/(r!(q-r)!)

I've gotten nowhere with this, and if this is because there is no
simple answer, please please tell me.
