For x0, simplify sqrt(x^3 + x^2) / x do you just simplify the interior and then -sqrt( ) ??

Factor an x^2 from the numerator: $\displaystyle \frac{\sqrt{x^2 ( x + 1)}}{x}$ Then write the square root as a product of the square roots of $\displaystyle x^2$ and $\displaystyle x+1$ Good luck!
so you then just cancel out x on top and bottom and are left with -sqrt(x-1) ?
Yes. It would be $\displaystyle -\sqrt{x+1}$.
