The solution

You have entered [src]

 x - 1  
--------
       2
(x + 3)

$$\frac{x - 1}{\left(x + 3\right)^{2}}$$

(x - 1)/(x + 3)^2

Detail solution

Apply the quotient rule, which is:

$\frac{d}{d x} \frac{f{\left(x \right)}}{g{\left(x \right)}} = \frac{- f{\left(x \right)} \frac{d}{d x} g{\left(x \right)} + g{\left(x \right)} \frac{d}{d x} f{\left(x \right)}}{g^{2}{\left(x \right)}}$

$f{\left(x \right)} = x - 1$ and $g{\left(x \right)} = \left(x + 3\right)^{2}$ .

To find $\frac{d}{d x} f{\left(x \right)}$ :
1. Differentiate $x - 1$ term by term:
  1. The derivative of the constant $-1$ 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. Let $u = x + 3$ .
2. Apply the power rule: $u^{2}$ goes to $2 u$
3. Then, apply the chain rule. Multiply by $\frac{d}{d x} \left(x + 3\right)$ :
  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: $1$
  The result of the chain rule is:
  
  $2 x + 6$
Now plug in to the quotient rule:

$\frac{- \left(x - 1\right) \left(2 x + 6\right) + \left(x + 3\right)^{2}}{\left(x + 3\right)^{4}}$
Now simplify:

$\frac{5 - x}{\left(x + 3\right)^{3}}$

The answer is:

$\frac{5 - x}{\left(x + 3\right)^{3}}$
