Solve \begin {gather*} \boxed {y^{\prime }-\frac {2 y^{6} \left (1+4 x y^{2}+y^{2}\right )}{y^{3}+4 y^{5} x +y^{5}+2+24 x y^{2}+96 y^{4} x^{2}+128 x^{3} y^{6}}=0} \end {gather*}

Solution by Maple

dsolve(diff(y(x),x) = 2*y(x)^6*(1+4*x*y(x)^2+y(x)^2)/(y(x)^3+4*y(x)^5*x+y(x)^5+2+24*x*y(x)^2+96*x^2*y(x)^4+128*x^3*y(x)^6),y(x), singsol=all)
