for this we only have solutions $b=-a,c=0$ and $b=a,c=2a$. We perform the next step,   \begin{equation}  \frac{2x}{ \frac{2x^3}{  x+\frac{\frac{a+b}{2}}{  x+\frac{\frac{(a-b)^2}{a+b}}{  x+\frac{\frac{2ab}{a+b}}{  x}}}} -2 \Leftrightarrow \frac{x}{x+\frac{c}{x}} -1 -2x^2 + a + b -\frac{x^2}{x+\frac{c}{x}} -x^2 +c =0  \end{equation}
