Okay, the binomial theorem tells us the general term in this expansion will be:

Now, in order for this term to be independent of*x*, to what must the exponent on*x*be equal? - January 16th 2013, 10:40 PMianmRe: Problem With Binomial Coefficients

Yes, correct on both counts! :D

So, what would the value of that term be? - January 16th 2013, 10:46 PMianmRe: Problem With Binomial Coefficients
