    Exclamation Partial Fractions Again =p

    Hey guys

    For the partial fraction:

    \frac{2x^2 + x + 6}{x^2 -4}

    How exactly does it become:

    2 + \frac{4}{x-2} - \frac{3}{x+2}

    I have no clue how the "2" appears.

    Please help?

    Thanx a lot!

    Long division gives

    \frac{2x^2 + x + 6}{x^2 - 4} = 2 + \frac{x + 14}{x^2 - 4}.


    Now use Partial Fractions on the \frac{x + 14}{x^2 - 4}.
