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

((x - 3)/(x + 2))^3

Detail solution

Let $u = \frac{x - 3}{x + 2}$ .
Apply the power rule: $u^{3}$ goes to $3 u^{2}$
Then, apply the chain rule. Multiply by $\frac{d}{d x} \frac{x - 3}{x + 2}$ :
1. Apply the quotient rule, which is:
  
  $\frac{d}{d x} \frac{f{\left(x \right)}}{g{\left(x \right)}} = \frac{- f{\left(x \right)} \frac{d}{d x} g{\left(x \right)} + g{\left(x \right)} \frac{d}{d x} f{\left(x \right)}}{g^{2}{\left(x \right)}}$
  
  $f{\left(x \right)} = x - 3$ and $g{\left(x \right)} = x + 2$ .
  
  To find $\frac{d}{d x} f{\left(x \right)}$ :
  1. Differentiate $x - 3$ term by term:
    1. The derivative of the constant $-3$ is zero.
    2. Apply the power rule: $x$ goes to $1$
    The result is: $1$
  To find $\frac{d}{d x} g{\left(x \right)}$ :
  1. Differentiate $x + 2$ term by term:
    1. The derivative of the constant $2$ is zero.
    2. Apply the power rule: $x$ goes to $1$
    The result is: $1$
  Now plug in to the quotient rule:
  
  $\frac{5}{\left(x + 2\right)^{2}}$
The result of the chain rule is:

$\frac{15 \left(x - 3\right)^{2}}{\left(x + 2\right)^{2} \left(x + 2\right)^{2}}$
Now simplify:

$\frac{15 \left(x - 3\right)^{2}}{\left(x + 2\right)^{4}}$

The answer is:

$\frac{15 \left(x - 3\right)^{2}}{\left(x + 2\right)^{4}}$
