Resolver a (complex solution)
a=\frac{16x}{\left(x+1\right)^{2}}
x\neq 0\text{ and }x\neq -1\text{ and }arg(\frac{4x^{2}+4x}{\left(x+1\right)^{2}})<\pi
Resolver x (complex solution)
\left\{\begin{matrix}x=\frac{\left(\sqrt{4-a}+2\right)^{2}}{a}\text{, }&a\neq 0\text{ and }arg(\sqrt{4-a}+2)<\pi \\x=-\frac{a+4\sqrt{4-a}-8}{a}\text{, }&arg(-\sqrt{4-a}+2)<\pi \text{ and }a\neq 0\end{matrix}\right.
Resolver a
a=\frac{16x}{\left(x+1\right)^{2}}
