    Re: Simplify the following expression:

    Do you mean s^2 and t^2 instead of s2 and t2 ?

    Do you understand that s/s^2 = 1/s ?

    in future, use parentheses to group terms and carets (^) to indicate exponents ...



    common denominator is $s^2-t^2 = (s+t)(s-t)$ ...

    $\dfrac{2st}{s^2-t^2} + \dfrac{s-t}{s^2-t^2} - \dfrac{4(s+t)}{s^2-t^2}$

    ... take it from here?

    Re: Simplify the following expression:

    I'm getting answer of (2st + 5s + 3t) / (s^2 - t ^ 2).

    Is that accurate?

    $\dfrac{2st+(s-t)-4(s+t)}{s^2-t^2}$
