Solve for x
\left\{\begin{matrix}x\neq 3\text{, }&p=-6\\x\neq -3\text{, }&p=6\\x\in \mathrm{R}\text{, }&|p|<6\\x\in \left(\frac{\sqrt{p^{2}-36}-p}{2},\infty\right)\cup \left(-\infty,\frac{-\sqrt{p^{2}-36}-p}{2}\right)\text{, }&|p|>6\end{matrix}\right.
Solve for p
\left\{\begin{matrix}p>-x-\frac{9}{x}\text{, }&x>0\\p\in \mathrm{R}\text{, }&x=0\\p<-x-\frac{9}{x}\text{, }&x<0\end{matrix}\right.
