If we have something like x/((x+1)(x+2)) we could decompose it into a/(x+1) +b/(x+2)

If we had something like x/(x+1)^2 we could decompose it into a/(x+1) + b/(x+1)^2

We use a different procedure when there is a square in part of the polynomial in the denominator.

What I don’t understand is why in the second case it wouldn’t be split into a/(x+1) + b/(x+1).

x/(x+1)^2 can be written as x/(x+1)(x+1). Then couldn’t we just use the procedure used in the first case?
