1/(x^2 - 2*x)
Detail solution
  1. Let u=x22xu = x^{2} - 2 x.

  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(x22x)\frac{d}{d x} \left(x^{2} - 2 x\right):

    1. Differentiate x22xx^{2} - 2 x term by term:

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

      2. The derivative of a constant times a function is the constant times the derivative of the function.

        1. Apply the power rule: xx goes to 11

        So, the result is: 2-2

      The result is: 2x22 x - 2

    The result of the chain rule is:

    2x2(x22x)2- \frac{2 x - 2}{\left(x^{2} - 2 x\right)^{2}}

  4. Now simplify:

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


The answer is:

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