Hi! Can I please have some help with the below?

When you integrate nCn x^n,
is it nCn [ (-1)^n / (n+1) ]?
And, if so, how did you get it?

Also, is nC2 = [ n(n-1) / 2 ]?
Again, if so, how did you get it?

Thank you!

Because is a constant, it plays no role in the integration.

Thanks guys! So it's NOT (-1)^n BUT x^(n+1)! I thought so!
