Question 890507
That cannot be understood when seen in the static field display.  The composing field gives better sense for what you are asking.

1.             1
--------  + -------
2(x+1).    X-1
____________
1.             1
-------- + ---------
X2-1.      X+1 


Still does not look right.  That still needs to be completely adjusted rewritten.



You very likely want what is in plain text, this:
(1/(2(x+1))+1/(x-1))/(1/(x^2-1)+1/(x+1))


As rendered, should look like this:
{{{(1/(2(x+1))+1/(x-1))/(1/(x^2-1)+1/(x+1))}}}


If this is what you really have as your starting expression, then help will be possible.
