    monster problem

    x^2-(-6x-6) over x^2+7x+6 added to -5x^2-4+8x over -6-7x-x^2


    I know you have to factor -1 to get the solution but I just can't put it together.

    I know you have to factor -1 to get the solution but I just can't put it together.
    \frac{x^2-(-6x-6)}{x^2+7x+6}+\frac{-5x^2-4+8x}{-6-7x-x^2}

    Factoring out and cancelling a negative one from the Num. and Den. of the second term gives...
    = \frac{x^2+6x+6}{x^2+7x+6}+\frac{5x^2-8x+4}{x^2+7x+6}

    Now since we have the same Den. we can add

    \frac{x^2+6x+6+5x^2-8x+4}{x^2+7x+6}

    Can you finish?
