Help in simplifying expression

Hi!

I have a really long expression 
which has Sqrt and squared terms 
each of which is a polynomial in 
four variables.

I know this monster is equal to 
zero.  I tried a numerical check 
with a few random values.

Theory says it is zero too.

But I can't get it to simplify 
algebraically to zero.

Any suggestions are welcome.

It is in the next post.

Thanks
Vlad.
