The given expression is:

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

### Let's simplify this step by step:

1. **Factorize and group terms**:
   \[
   \frac{-\frac{1}{2}x(1 - x)^{-\frac{1}{2}} + (1 - x)^{\frac{1}{2}}x}{x^2}
   \]
   
   We can factor out \(x\) from both terms in the numerator:
   \[
   = \frac{x \left( -\frac{1}{2}(1 - x)^{-\frac{1}{2}} + (1 - x)^{\frac{1}{2}} \right)}{x^2}
   \]

2. **Cancel \(x\) in numerator and denominator**:
   \[
   = \frac{ -\frac{1}{2}(1 - x)^{-\frac{1}{2}} + (1 - x)^{\frac{1}{2}}}{x}
   \]

3. **Simplify further**:
   Now we have two terms involving powers of \(1 - x\):
   \[
   = \frac{ (1 - x)^{\frac{1}{2}} - \frac{1}{2}(1 - x)^{-\frac{1}{2}} }{x}
   \]

### Final simplified expression:

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

This is the simplified version of the given expression.
