    Post Can somebody help me with algebra 2?

    [(y-1)/ (y^2 - 3y - 10)] - [(2y) / (y^2 + 2y - 35)] Simplify. Please show me how you did it step by step. Thank you so much!!

    (y-1)/((y-5)(y+2)) - 2y/((y-5)(y+7))

    ((y-1)(y+7))/((y-5)(y+2)(y+7)) - 2y(y+2)/((y-5)(y+2)(y+7))

    (y^2 + 6y - 7)/((y-5)(y+2)(y+7)) - (4y^2 + 4y)/((y-5)(y+2)(y+7))

    (-3y^2 + 2y - 7)/((y-5)(y+2)(y+7))

    (y^2 + 6y - 7)/((y-5)(y+2)(y+7)) - (4y^2 + 4y)/((y-5)(y+2)(y+7))

    (-3y^2 + 2y - 7)/((y-5)(y+2)(y+7))

    \frac{y-1}{y^2-3y-10}-\frac{2y}{y^2+2y-35}

    \frac{y-1}{(y-5)(y+2)}-\frac{2y}{(y+7)(y-5)}

    LCD=(y-5)(y+2)(y+7)

    \frac{(y-1)(y+7)}{(y-5)(y+2)(y+7)}-\frac{2y(y+2)}{(y-5)(y+2)(y+7)}

    \frac{(y-1)(y+7)-2y(y+2)}{(y-5)(y+2)(y+7)}

    \frac{y^2+6y-7-2y^2-4y}{(y-5)(y+2)(y+7)}

    \frac{-y^2+2y-7}{(y-5)(y+2)(y+7)}

    Oops! Seems simple multiplication is beyond me :P

    Thought the final answer looked a bit iffy.
