Just write down the first two binomial coefficients using that definition above, combine them together and use some tricks to get it into the required form.

Tricks like:
[eqn](n-1)!=\frac{n!}{n}[/eqn]
etc

Also, it helps to write down the required form in form of the definition so that you know what you're trying to prove

Concordo. Grazie cmq
Studi matematica?

Thank you
