Sorry,
 
But it was not my fault, it is some website problem. I have written the correct.
 
 
You have to make quantity (in bracket) positive.
 
hence
 
x/(x^2 – 1)
 
also
x / (x^2 – 1) > 0
 
 
You will get your answer. In case of any difficulty, Please feel free to ask.

x/(x2-1)>0
x(x+1)(x-1)>0
by wavy curve method,
x belongs to(-1,0)U(1,infinete)
as denominator should not be zero and log domain is always positive denominator always greater than zero
x2-1>0
(x+1)(x-1)>0
by wavy curve method,
x belongs to (-infinete,-1)U(1,infinete)
we have to consider common domain so,
x belongs to (1,infinete)
please aproove...
