New expression

New expression is being posted today. This one is very interesting. You add up two binomial statements expressions in some way and what you get is very surprising indeed. Zero !! It is not actually zero but approximately zero. 

How about that ?

Here is the expression

The above equation is valid whether n1 is negative or n2 is negative. The only thing is modulus n2 is lesser than modulus n1. I have checked.

Here are the Wolfram Alpha screenshots with an example to show that the statement is valid.

Have a very nice day !!
