-------
2*x - 1

$$\frac{\sqrt{x}}{2 x - 1}$$

sqrt(x)/(2*x - 1)

Detail solution

Apply the quotient rule, which is:

$\frac{d}{d x} \frac{f{\left(x \right)}}{g{\left(x \right)}} = \frac{- f{\left(x \right)} \frac{d}{d x} g{\left(x \right)} + g{\left(x \right)} \frac{d}{d x} f{\left(x \right)}}{g^{2}{\left(x \right)}}$

$f{\left(x \right)} = \sqrt{x}$ and $g{\left(x \right)} = 2 x - 1$ .

To find $\frac{d}{d x} f{\left(x \right)}$ :
1. Apply the power rule: $\sqrt{x}$ goes to $\frac{1}{2 \sqrt{x}}$
To find $\frac{d}{d x} g{\left(x \right)}$ :
1. Differentiate $2 x - 1$ term by term:
  1. The derivative of the constant $-1$ is zero.
  2. The derivative of a constant times a function is the constant times the derivative of the function.
    1. Apply the power rule: $x$ goes to $1$
    So, the result is: $2$
  The result is: $2$
Now plug in to the quotient rule:

$\frac{- 2 \sqrt{x} + \frac{2 x - 1}{2 \sqrt{x}}}{\left(2 x - 1\right)^{2}}$
Now simplify:

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

The answer is:

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