Evaluate (complex solution)
Cbr+3=16C\text{ and }16C=-r
Solve for r
\left\{\begin{matrix}r=\frac{4\left(\sqrt{3b+4}+2\right)}{b}\text{, }&b\neq 0\text{ and }b\geq -\frac{4}{3}\text{ and }C=-\frac{\sqrt{3b+4}+2}{4b}\\r=\frac{4\left(-\sqrt{3b+4}+2\right)}{b}\text{, }&b\neq 0\text{ and }b\geq -\frac{4}{3}\text{ and }C=\frac{8\sqrt{3b+4}-16}{32b}\\r=-3\text{, }&C=\frac{3}{16}\text{ and }b=0\end{matrix}\right.
Solve for b
b=\frac{16\left(r+3\right)}{r^{2}}
C=-\frac{r}{16}\text{ and }r\neq 0
