Detail solution

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

$- 2 x e^{- x^{2}}$

The answer is:

$- 2 x e^{- x^{2}}$
