     x      
------------
 2          
x  - 3*x + 2

$$\frac{x}{\left(x^{2} - 3 x\right) + 2}$$

x/(x^2 - 3*x + 2)

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 $g{\left(x \right)} = x^{2} - 3 x + 2$ .

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. Differentiate $x^{2} - 3 x + 2$ term by term:
  1. The derivative of the constant $2$ is zero.
  2. Apply the power rule: $x^{2}$ goes to $2 x$
  3. 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: $-3$
  The result is: $2 x - 3$
Now plug in to the quotient rule:

$\frac{x^{2} - x \left(2 x - 3\right) - 3 x + 2}{\left(x^{2} - 3 x + 2\right)^{2}}$

The answer is:

$\frac{x^{2} - x \left(2 x - 3\right) - 3 x + 2}{\left(x^{2} - 3 x + 2\right)^{2}}$
