Detail solution
  1. Apply the quotient rule, which is:

    ddxf(x)g(x)=f(x)ddxg(x)+g(x)ddxf(x)g2(x)\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(x)=x2f{\left(x \right)} = x^{2} and g(x)=(x1)2g{\left(x \right)} = \left(x - 1\right)^{2}.

    To find ddxf(x)\frac{d}{d x} f{\left(x \right)}:

    1. Apply the power rule: x2x^{2} goes to 2x2 x

    To find ddxg(x)\frac{d}{d x} g{\left(x \right)}:

    1. Let u=x1u = x - 1.

    2. Apply the power rule: u2u^{2} goes to 2u2 u

    3. Then, apply the chain rule. Multiply by ddx(x1)\frac{d}{d x} \left(x - 1\right):

      1. Differentiate x1x - 1 term by term:

        1. The derivative of the constant 1-1 is zero.

        2. Apply the power rule: xx goes to 11

        The result is: 11

      The result of the chain rule is:

      2x22 x - 2

    Now plug in to the quotient rule:

    x2(2x2)+2x(x1)2(x1)4\frac{- x^{2} \left(2 x - 2\right) + 2 x \left(x - 1\right)^{2}}{\left(x - 1\right)^{4}}

  2. Now simplify:

    2x(x(1x)+(x1)2)(x1)4\frac{2 x \left(x \left(1 - x\right) + \left(x - 1\right)^{2}\right)}{\left(x - 1\right)^{4}}


The answer is:

2x(x(1x)+(x1)2)(x1)4\frac{2 x \left(x \left(1 - x\right) + \left(x - 1\right)^{2}\right)}{\left(x - 1\right)^{4}}
