jukeu2buhu Group Title

Im trying to finish an assignment, but learning this section is online is a little difficult, can someone help me? The first question asks me to simplify [(t^2+6t)/(t-1)]-[(7)/(t-1)] and I've simplified it to [(t(t+6))/(t-1)]+[(-7)/(t-1)] but I dont know what to do here. I have common denominators and I think I can cancel t out from the left left side problem from the top and bottom but Im not sure. Help please?

    \[\frac{ t^2+6t }{ t-1 }-\frac{7}{t-1}=\frac{ t^2+6t - 7}{ t-1 }=\frac{(t-1)(t+6)}{t-1}=t+6\]

    you could, but that wouldn't do anything. You have yourself a quadratic in the numerator, so just factor the whole thing. That way the denominator cancels out

    ok so for example \[[(4x+4)/(x(x+1)]-[(11x)/(x(x+1)] is then [(4x+4-11x)/(x(x+1)]\]

    yes, and you have a quadratic in the numerator and factor this to cancel with the denominator

    so its (4-7x)/(x(x+1))
