Detail solution

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

$2 \cdot \left(2 x^{2} - 1\right) e^{- x^{2}}$

The answer is:

$2 \cdot \left(2 x^{2} - 1\right) e^{- x^{2}}$
