\begin{align*} \left (\left (4 a x +\lambda s \right ) y+\left (3 s +4 \lambda \right ) x \right ) y^{\prime }&=\frac {3 a y^{2}}{2}+6 \lambda +2 s +2 x \end{align*}

✗ Maple

ode:=((4*a*x+lambda*s)*y(x)+(3*s+4*lambda)*x)*diff(y(x),x) = 3/2*a*y(x)^2+6*lambda+2*s+2*x; 
dsolve(ode,y(x), singsol=all);
 

\[ \text {No solution found} \]

✗ Mathematica

ode=((4*a*x+\[Lambda]*s)*y[x]+(4*\[Lambda]+3*s)*x)*D[y[x],x]==3/2*a*y[x]^2+2*(3*\[Lambda]+s)+2*x;
