x - \/  x  - x

$$x - \sqrt{x^{2} - x}$$

x - sqrt(x^2 - x)

Detail solution

Differentiate $x - \sqrt{x^{2} - x}$ term by term:
1. Apply the power rule: $x$ goes to $1$
2. The derivative of a constant times a function is the constant times the derivative of the function.
  1. Let $u = x^{2} - x$ .
  2. Apply the power rule: $\sqrt{u}$ goes to $\frac{1}{2 \sqrt{u}}$
  3. Then, apply the chain rule. Multiply by $\frac{d}{d x} \left(x^{2} - x\right)$ :
    1. Differentiate $x^{2} - x$ term by term:
      1. Apply the power rule: $x^{2}$ goes to $2 x$
      2. The derivative of a constant times a function is the constant times the derivative of the function.
        
        Apply the power rule: $x$ goes to $1$
        
        So, the result is: $-1$
      The result is: $2 x - 1$
    The result of the chain rule is:
    
    $\frac{2 x - 1}{2 \sqrt{x^{2} - x}}$
  So, the result is: $- \frac{2 x - 1}{2 \sqrt{x^{2} - x}}$
The result is: $- \frac{2 x - 1}{2 \sqrt{x^{2} - x}} + 1$
Now simplify:

$\frac{- x + \sqrt{x \left(x - 1\right)} + \frac{1}{2}}{\sqrt{x \left(x - 1\right)}}$

The answer is:

$\frac{- x + \sqrt{x \left(x - 1\right)} + \frac{1}{2}}{\sqrt{x \left(x - 1\right)}}$
