1. ## simplifying

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:

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

Then write the square root as a product of the square roots of $x^2$ and $x+1$

Good luck!

3. so you then just cancel out x on top and bottom and are left with -sqrt(x-1) ?

4. Yes. It would be $-\sqrt{x+1}$.
