Find all values of r such that (r - 3)/sqrt(r) = -2*sqrt(r).

Just a side note, make sure to put $around your LaTeX so it renders properly, and put \sqrt{} instead of sqrt(). Multiplying both sides by$\sqrt{r}$gives$r-3=-2*\sqrt{r}*\sqrt{r}$. Simplifying the right hand side gives$r-3=-2r$, and subtracting r from both sides gives$-3=-3r$. Dividing by -3 gives$\boxed{r=1}\$
