- In this video, we discuss the combinatorial proof for why 2n choose 2 is same as 2 * n choose 2 + n square. A combinatorial proof is given for the identity C(2n,2) = 2*C(n,2) + n^2 .

Thank you for this video! understood it perfectly thanks to you
you're cooking me sreyas
Can you prove that n! = sum(C(n,j)*j^(n)*(-1)^(n-j)) from j=0 to n
nice!!
Thank u so much sir.
Thank you!
I thing, for all n can explain to 2*C(n+1, 2)
