Transform

Detail solution

Apply the quotient rule, which is:

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

$f{\left(x \right)} = \left(x - 3\right)^{2}$ and $g{\left(x \right)} = 4 x - 4$ .

To find $\frac{d}{d x} f{\left(x \right)}$ :
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:
  
  $2 x - 6$
To find $\frac{d}{d x} g{\left(x \right)}$ :
1. Differentiate $4 x - 4$ term by term:
  1. The derivative of the constant $-4$ is zero.
  2. The derivative of a constant times a function is the constant times the derivative of the function.
    1. Apply the power rule: $x$ goes to $1$
    So, the result is: $4$
  The result is: $4$
Now plug in to the quotient rule:

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

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

The answer is:

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