My question reads:
If n is a positive integer and n > 1, prove that C(n,2) + C(n-1,2) is a perfect square.
Anyway, I went ahead and simplified the statement, which brought it to this:
In this form, it's fairly obvious that for any selected value of an integer n greater than one, it will be a perfect square.
What I'm wondering is if there's a better way to conclude the proof, or if that answer seems suitable.
Thank you for your time. (Happy)
