       x

(x - 1)*(x - 4)

\frac{x}{\left(x - 4\right) \left(x - 1\right)}

x/(((x - 1)*(x - 4)))

Detail solution

Apply the quotient rule, which is:

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

$f{\left(x \right)} = x$ and $g{\left(x \right)} = \left(x - 4\right) \left(x - 1\right)$ .

To find $\frac{d}{d x} f{\left(x \right)}$ :
1. Apply the power rule: $x$ goes to $1$
To find $\frac{d}{d x} g{\left(x \right)}$ :
1. Apply the product rule:
  
  $\frac{d}{d x} f{\left(x \right)} g{\left(x \right)} = f{\left(x \right)} \frac{d}{d x} g{\left(x \right)} + g{\left(x \right)} \frac{d}{d x} f{\left(x \right)}$
  
  $f{\left(x \right)} = x - 1$ ; to find $\frac{d}{d x} f{\left(x \right)}$ :
  1. Differentiate $x - 1$ term by term:
    1. The derivative of the constant $-1$ is zero.
    2. Apply the power rule: $x$ goes to $1$
    The result is: $1$
  $g{\left(x \right)} = x - 4$ ; to find $\frac{d}{d x} g{\left(x \right)}$ :
  1. Differentiate $x - 4$ term by term:
    1. The derivative of the constant $-4$ is zero.
    2. Apply the power rule: $x$ goes to $1$
    The result is: $1$
  The result is: $2 x - 5$
Now plug in to the quotient rule:

$\frac{- x \left(2 x - 5\right) + \left(x - 4\right) \left(x - 1\right)}{\left(x - 4\right)^{2} \left(x - 1\right)^{2}}$

The answer is:

\frac{- x \left(2 x - 5\right) + \left(x - 4\right) \left(x - 1\right)}{\left(x - 4\right)^{2} \left(x - 1\right)^{2}}
