Partial Fractions: Solving Homework Equations

Click For Summary
The discussion focuses on the process of partial fraction decomposition for the expression (x^4 - 2x^3 + x^2 + 2x - 1) / (x^2 - 2x + 1). The initial division yields x^2 + (2x - 1) / (x^2 - 2x + 1), which is a correct first step. However, the decomposition is incomplete as the denominator factors into (x - 1)(x - 1), indicating a need for further breakdown. Participants emphasize the importance of reviewing partial fraction techniques to fully resolve the expression. The conversation highlights the necessity of understanding factorization in achieving a complete solution.

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.

It's right, but it's not a complete partial fraction expansion. x^2-2x+1 factors into (x-1)(x-1). Review partial fractions.
