\begin{align*} 8 {y^{\prime }}^{3}+12 {y^{\prime }}^{2}&=27 x +27 y \end{align*}

Solution by Maple

Time used: 0.101 (sec). Leaf size: 43

dsolve(8*diff(y(x),x)^3+12*diff(y(x),x)^2 = 27*x+27*y(x),y(x), singsol=all)
 
\begin{align*} y \left (x \right ) &= -x +\frac {4}{27} \\ y \left (x \right ) &= \left (-x +c_{1} \right ) \sqrt {-c_{1} +x}-c_{1} \\ y \left (x \right ) &= \left (-c_{1} +x \right )^{{3}/{2}}-c_{1} \\ \end{align*}

Solution by Mathematica
