Mathematics help please!

Hi,
i've been trying to work on this question but can't get anywhere with it. Any help at all would be greatly appreciated please :smile:
(excuse how it's written - hard to write maths on here)

Deduce that:
2n choose n = (sum from k=0 to n) (n choose k)^2

As i said, any help would be appreciated greatly.
Many thanks

This wouldn't happen to be coursework per chance?
