It looks like you're trying to express a mathematical expression involving fractions and functions, but it seems a bit jumbled due to formatting. To help you better, let's clarify the expression you have.

Here's what I understand based on your input:

You have an expression that looks something like this:

\[
\frac{\frac{1}{1-x} + \frac{2}{x+1} - \frac{5-x}{(1-x)^2}}{1 - \frac{2x}{x^2 - 1}}
\]

Could you please confirm if this interpretation is correct? If not, could you either rewrite or clarify the expression further?

Once clarified, I would be happy to help you simplify or analyze the expression as needed!
