Hello, I am just teaching myself partial fraction decomposition.
I am pretty sure I have it sorted out, but can someone please cast their eyes over this quickly to confirm if correct or not ?
Thanks kindly.
Hello, fran1942!
Please confirm: .$\displaystyle \frac{5x-1}{(x-2)(x+1)^2} \;=\;\frac{1}{x-2} - \frac{1}{x+1} + \frac{2}{(x+1)^2}$
You can check your results yourself.
Just combine your three fractions . . .
Do you know how obsolete this question is?
Look at this webpage.
Computer algebra systems have rendered the topic of partial fractions obsolete.
