    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: . \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.
    If you are self-studying make wolframalpha.com your friend.
