Solve for k (complex solution)
k=-\frac{i\sqrt{-6x-9}}{x}
k=\frac{i\sqrt{-6x-9}}{x}\text{, }x\neq 0
Solve for k
k=\frac{\sqrt{6x+9}}{|x|}
k=-\frac{\sqrt{6x+9}}{|x|}\text{, }x\geq -\frac{3}{2}\text{ and }x\neq 0
Solve for x
\left\{\begin{matrix}x=\frac{3\left(\sqrt{k^{2}+1}+1\right)}{k^{2}}\text{; }x=\frac{3\left(-\sqrt{k^{2}+1}+1\right)}{k^{2}}\text{, }&k\neq 0\\x=-\frac{3}{2}\text{, }&k=0\end{matrix}\right.
