Homework Statement
[itex]\int \frac{-2x + 4}{(x-1)^{(2)}(x^{(2)}+1)}[/itex]
Homework Equations
The Attempt at a Solution
I've done the problem a couple times but the answers keep coming out differently so I'm assuming I am messing up the setup.
This is what I have for the first part of the setup:
[itex] -2x + 4 = A(x-1)^{(2)}(x^{(2)}+1) + B(x-1)(x^{(2)}+1) + (Cx+D)*(x-1)(x-1)^{(2)} [/itex]
Once expanded :
[itex] -2x + 4 = Ax^4 - A2x^3 + A2x^2 - A2x + A + Bx^3 -Bx^2 +Bx - B + Cx^4 - C3x^3 + C3x^2 - Cx[/itex]
[itex] +Dx^3 - D3x^2 + D3x - D [/itex]Can anyone let me know if I'm right up to this point?
