Transform

Detail solution

Apply the product rule:

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

$f{\left(x \right)} = x^{3}$ ; to find $\frac{d}{d x} f{\left(x \right)}$ :
1. Apply the power rule: $x^{3}$ goes to $3 x^{2}$
$g{\left(x \right)} = \left(x + 2\right)^{2}$ ; to find $\frac{d}{d x} g{\left(x \right)}$ :
1. Let $u = x + 2$ .
2. Apply the power rule: $u^{2}$ goes to $2 u$
3. Then, apply the chain rule. Multiply by $\frac{d}{d x} \left(x + 2\right)$ :
  1. Differentiate $x + 2$ term by term:
    1. Apply the power rule: $x$ goes to $1$
    2. The derivative of the constant $2$ is zero.
    The result is: $1$
  The result of the chain rule is:
  
  $2 x + 4$
The result is: $x^{3} \cdot \left(2 x + 4\right) + 3 x^{2} \left(x + 2\right)^{2}$
Now simplify:

$x^{2} \left(x + 2\right) \left(5 x + 6\right)$

The answer is:

$x^{2} \left(x + 2\right) \left(5 x + 6\right)$
