Transform

Detail solution

Apply the product rule:

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

$f{\left(x \right)} = 3 x^{2} + 2$ ; to find $\frac{d}{d x} f{\left(x \right)}$ :
1. Differentiate $3 x^{2} + 2$ 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: $6 x$
  2. The derivative of the constant $2$ is zero.
  The result is: $6 x$
$g{\left(x \right)} = \log{\left(x \right)}^{2}$ ; to find $\frac{d}{d x} g{\left(x \right)}$ :
1. Let $u = \log{\left(x \right)}$ .
2. Apply the power rule: $u^{2}$ goes to $2 u$
3. Then, apply the chain rule. Multiply by $\frac{d}{d x} \log{\left(x \right)}$ :
  1. The derivative of $\log{\left(x \right)}$ is $\frac{1}{x}$ .
  The result of the chain rule is:
  
  $\frac{2 \log{\left(x \right)}}{x}$
The result is: $6 x \log{\left(x \right)}^{2} + \frac{2 \cdot \left(3 x^{2} + 2\right) \log{\left(x \right)}}{x}$
Now simplify:

$\frac{2 \cdot \left(3 x^{2} \log{\left(x \right)} + 3 x^{2} + 2\right) \log{\left(x \right)}}{x}$

The answer is:

$\frac{2 \cdot \left(3 x^{2} \log{\left(x \right)} + 3 x^{2} + 2\right) \log{\left(x \right)}}{x}$
