f(x)= (-2x^2 +2)/(x^2 +2x +1)
how does this simplify any further?

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

How can I do that with this?

4. 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".

5. $\frac{-2x^2+2}{x^2+2x+1}
$

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

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

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