/ 2    \ 
\x  + 1/

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

(x^2 + 1)^2

Detail solution

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

$2 x \left(2 x^{2} + 2\right)$
Now simplify:

$4 x \left(x^{2} + 1\right)$

The answer is:

$4 x \left(x^{2} + 1\right)$
