    factoring the numerator and denominator will tell you if the rational expression simplifies further.

    well, I may have made a mistake, but I was able to factor the equation to

    \frac{2(-x^2+1)}{(x+1)^2}

    But that doesn't simplify any further, unless you consider it being factored as being "simplified".

    \frac{-2x^2+2}{x^2+2x+1}<br />

    \frac{-2(x^2-1)}{(x+1)^2}

    \frac{-2(x+1)(x-1)}{(x+1)^2}

    \frac{-2(x-1)}{x+1}
