Find y' of $2x^2+x+xy=1
$\begin{array}{lll}
\textit{separate variables}
&xy=2x^2+x+1 \implies y=\dfrac{2x^2+x+1}{x}\implies 2x+1+x^{-1}
&(1)\\ \\
\textit{differencate both sides}
&y'=2-\dfrac{1}{x^2}
&(2)
\end{array}
ok it seems we can do any implicit differentiation by separation or not?
I think I got the right answer hopefully
