E^(-x^2 - 2)

Detail solution

Let $u = - x^{2} - 2$ .
The derivative of $e^{u}$ is itself.
Then, apply the chain rule. Multiply by $\frac{d}{d x} \left(- x^{2} - 2\right)$ :
1. Differentiate $- x^{2} - 2$ term by term:
  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: $- 2 x$
  2. The derivative of the constant $-2$ is zero.
  The result is: $- 2 x$
The result of the chain rule is:

$- 2 x e^{- x^{2} - 2}$
Now simplify:

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

The answer is:

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