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

The integral to be solved is:

\[
\int \frac{-2x+4}{\left(x^2+1\right)\left(x-1\right)^2} dx
\]

### Solution Outline

We will solve this using **partial fraction decomposition**. The idea is to express the integrand as a sum of simpler fractions, which can then be integrated individually.

### Step 1: Partial Fraction Decomposition
We want to decompose:

\[
\frac{-2x+4}{(x^2+1)(x-1)^2}
\]

We assume the form:

\[
\frac{-2x+4}{(x^2+1)(x-1)^2} = \frac{A}{x-1} + \frac{B}{(x-1)^2} + \frac{Cx + D}{x^2+1}
\]

### Step 2: Multiply Both Sides by \((x^2+1)(x-1)^2\)
Multiplying through by the denominator clears the fractions:

\[
-2x + 4 = A(x-1)(x^2+1) + B(x^2+1) + (Cx+D)(x-1)^2
\]

Now expand both sides and collect like terms to solve for \(A\), \(B\), \(C\), and \(D\).
