    Correct Rational Expression?

    Hello, everybody. I did an exercise from a textbook I'm learning from and here is the rational expression which I'm required to add:

    <br /> <br />
\frac {6}{x + 3} - \frac {x + 4}{9 - x^2} + \frac {2x - 3}{9 - 6x + x^2}<br /> <br />

    Here is the answer which I got:

    <br /> <br />
\frac {9x^2 - 32x + 33}{(x + 3)(x - 3)^2}<br /> <br />

    I would very much appreciate if anyone can tell me whether or not I did this problem correctly, as there is no answer for it in the book. Thank you very much for your time. :]
