1/((x - 1)^2)
Detail solution
  1. Let u=(x1)2u = \left(x - 1\right)^{2}.

  2. Apply the power rule: 1u\frac{1}{u} goes to 1u2- \frac{1}{u^{2}}

  3. Then, apply the chain rule. Multiply by ddx(x1)2\frac{d}{d x} \left(x - 1\right)^{2}:

    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. Apply the power rule: xx goes to 11

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

        The result is: 11

      The result of the chain rule is:

      2x22 x - 2

    The result of the chain rule is:

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

  4. Now simplify:

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


The answer is:

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