Detail solution

The derivative of a constant times a function is the constant times the derivative of the function.
1. Let $u = \left(4 x + 1\right)^{2}$ .
2. Apply the power rule: $\frac{1}{u}$ goes to $- \frac{1}{u^{2}}$
3. Then, apply the chain rule. Multiply by $\frac{d}{d x} \left(4 x + 1\right)^{2}$ :
  1. Let $u = 4 x + 1$ .
  2. Apply the power rule: $u^{2}$ goes to $2 u$
  3. Then, apply the chain rule. Multiply by $\frac{d}{d x} \left(4 x + 1\right)$ :
    1. Differentiate $4 x + 1$ 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: $4$
      2. The derivative of the constant $1$ is zero.
      The result is: $4$
    The result of the chain rule is:
    
    $32 x + 8$
  The result of the chain rule is:
  
  $- \frac{32 x + 8}{\left(4 x + 1\right)^{4}}$
So, the result is: $- \frac{11 \left(32 x + 8\right)}{\left(4 x + 1\right)^{4}}$
Now simplify:

$\frac{88}{\left(- 4 x - 1\right)^{3}}$

The answer is:

\frac{88}{\left(- 4 x - 1\right)^{3}}
