Detail solution

The derivative of a constant times a function is the constant times the derivative of the function.
1. Let $u = \left(2 x + 3\right)^{2}$ .
2. Apply the power rule: $\frac{1}{u}$ goes to $- \frac{1}{u^{2}}$
3. Then, apply the chain rule. Multiply by $\frac{d}{d x} \left(2 x + 3\right)^{2}$ :
  1. Let $u = 2 x + 3$ .
  2. Apply the power rule: $u^{2}$ goes to $2 u$
  3. Then, apply the chain rule. Multiply by $\frac{d}{d x} \left(2 x + 3\right)$ :
    1. Differentiate $2 x + 3$ term by term:
      1. The derivative of a constant times a function is the constant times the derivative of the function.
        
        Apply the power rule: $x$ goes to $1$
        
        So, the result is: $2$
      2. The derivative of the constant $3$ is zero.
      The result is: $2$
    The result of the chain rule is:
    
    $8 x + 12$
  The result of the chain rule is:
  
  $- \frac{8 x + 12}{\left(2 x + 3\right)^{4}}$
So, the result is: $- \frac{3 \cdot \left(8 x + 12\right)}{\left(2 x + 3\right)^{4}}$
Now simplify:

$\frac{12}{\left(- 2 x - 3\right)^{3}}$

The answer is:

$\frac{12}{\left(- 2 x - 3\right)^{3}}$
