[tex]\frac{2x + 2}{x^2 - 2x + 1}dx[/tex]

2. Relevant equations

3. The attempt at a solution

I factorized the denominator and got [tex]\frac{2x + 2}{(x - 1)^2}[/tex] and I took a look at the solutions manual to see how they handled this but then I see this [tex]\frac{2x + 2}{(x - 1)^2} = \frac{A}{(x - 1)} + \frac{B}{(x - 1)^2}[/tex]. I'm lost how is the denominator of partial fraction B squared?
