The solution

 2          
x  + 3*x - 2
------------
   x - 1

$$\frac{\left(x^{2} + 3 x\right) - 2}{x - 1}$$

(x^2 + 3*x - 2)/(x - 1)

Detail solution

Apply the quotient rule, which is:

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

$f{\left(x \right)} = x^{2} + 3 x - 2$ and $g{\left(x \right)} = x - 1$ .

To find $\frac{d}{d x} f{\left(x \right)}$ :
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: $2 x + 3$
To find $\frac{d}{d x} g{\left(x \right)}$ :
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: $1$
Now plug in to the quotient rule:

$\frac{- x^{2} - 3 x + \left(x - 1\right) \left(2 x + 3\right) + 2}{\left(x - 1\right)^{2}}$
Now simplify:

$\frac{x^{2} - 2 x - 1}{x^{2} - 2 x + 1}$

The answer is:

$\frac{x^{2} - 2 x - 1}{x^{2} - 2 x + 1}$
