When you post formulas to this forum, USE PARENTHESES to show adequately the numerators and denominators in your formulas.

It is the RULE at this forum.

Otherwise, the formulas are ambiguous and unreadable.

The blind "copy and paste" method does not work.

You need to look into the formula in your source, to understand what does it mean (= to read it correctly), and then translate it
into the text format in your post USING PARENTHESES.

Are you trying to show x%2F%28x-1%29-1%2F%28x%5E2-x%29 ?


Simplest common denominator is x%5E2-x=x%28x-1%29. Simple fractions skills. Bring one of the expressions to higher terms.

%28x%2F%28x-1%29%29%28x%2Fx%29-1%2F%28x%5E2-x%29

continue from that...
