    ok one last one....

    even though by the time I get a reply or get back here it'll be too late. I think I might have copied this one wrong....

    t^2+5t - 7t-3
    t^2+7t+6...t^2+7-6

    Hello,

    maybe you mean:

    \frac{t^2 + 5t}{t^2+7t+6} - \frac{7t-3}{t^2+7t-6} . If so:

    Factor all numerators and denominators (if possible):

    \frac{t(t + 5)}{(t+1)(t+6)} - \frac{7t-3}{t^2+7t-6} = \frac{t(t+5)(t^2+7t-6)-(7t-3)(t+1)(t+6)}{(t+1)(t+6)(t^2+7t-6)}

    Expand the brackets in the numerator and collect like terms.

    In my opinion there must be a typo in the 2nd summand ...

    Yes, yes I did write the second summand wrong, I noticed it after working on another problem similar to it. thanks though
