\[ \boxed {{y^{\prime }}^{2}-2 y^{\prime } x=8 x^{2}} \]

Solution by Maple

Time used: 0.0 (sec). Leaf size: 21

dsolve(diff(y(x),x)^2-2*x*diff(y(x),x)-8*x^2=0,y(x), singsol=all)
 

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

Solution by Mathematica

Time used: 0.003 (sec). Leaf size: 25

DSolve[y'[x]^2-2*x*y'[x]-8*x^2==0,y[x],x,IncludeSingularSolutions -> True]
 

\begin{align*} y(x)\to -x^2+c_1 \\ y(x)\to 2 x^2+c_1 \\ \end{align*}
