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

Transform

Detail solution

Apply the product rule:

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

$f{\left(x \right)} = x^{3} - 2$ ; to find $\frac{d}{d x} f{\left(x \right)}$ :
1. Differentiate $x^{3} - 2$ term by term:
  1. Apply the power rule: $x^{3}$ goes to $3 x^{2}$
  2. The derivative of the constant $\left(-1\right) 2$ is zero.
  The result is: $3 x^{2}$
$g{\left(x \right)} = x^{2} + 1$ ; to find $\frac{d}{d x} g{\left(x \right)}$ :
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 is: $3 x^{2} \left(x^{2} + 1\right) + 2 x \left(x^{3} - 2\right)$
Now simplify:

$x \left(5 x^{3} + 3 x - 4\right)$

The answer is:

$x \left(5 x^{3} + 3 x - 4\right)$
