    Is this correct??

    Hello

    IS this correct? I have to perform the indicated operations and simplify

    [tex]\frac{1}{x+2}+\frac{1}{x^2-4}-\frac{2}{x^2-x-2} [/tex]

    This is my answer

    [tex]\frac{x^2+2x-5}{(x+2)(x-2)(x+1)}[/tex]

    Thanks

    Shouldn't the numerator of the answer be: [itex]x^2 - 2x - 5[/itex]?
