    integrate with respect to x this quadractic fractions?

    integrate with respect to x:

    2x - 9x + 1

    ( (x-1)(x+2) ) dx


    thats the best way i can think of laying it out without having to take a photo of the equation.

    Have no clue where to start its been years since i did these ... any help would be awesome?
    thanks

    You need to partial fraction the expression first. In this case it will break down into
    A/(x+2)+B/(x-1)+C/(x-1)^2
