dsolve(y(x)*(3-4*y(x))^2*diff(y(x),x)^2=4*(1-y(x)),y(x), singsol=all)
 

\begin{align*} y \left (x \right ) &= 1 \\ x +\frac {y \left (x \right )^{2} \left (y \left (x \right )-1\right )}{\sqrt {-y \left (x \right ) \left (y \left (x \right )-1\right )}}-c_{1} &= 0 \\ x -\frac {y \left (x \right )^{2} \left (y \left (x \right )-1\right )}{\sqrt {-y \left (x \right ) \left (y \left (x \right )-1\right )}}-c_{1} &= 0 \\ \end{align*}
