Hi All,
This is algebraic proof of Vandermonde's identity:
I am having some problem understanding how we reached the second last step and more importantly, last steps from revious steps.

I would be grateful if someone would elaborate it clearly.
Basically none that are relevant to answer my question.
I have no idea how we reached the last two steps.
Thank You.
