## Homework Statement

Write out the form of the partial fraction decomposition of not determine the numerical values of the coefficients.

## Homework Equations

x^4 -2x^3 + x^2 +2x -1 / x^2 -2x +1

## The Attempt at a Solution

I did the division and I got x^2 + ((2x-1)) / (x^2 -2x +1)

So I took

((2x-1)) / (x^2 -2x +1) = Ax + B / x^2 -2x +1

Is this right? It has been forever since I did these.
