Solve \begin {gather*} \boxed {y^{\prime }-y^{2} f \relax (x )+a \,{\mathrm e}^{\lambda x} g \relax (x ) y-a \lambda \,{\mathrm e}^{\lambda x}-a^{2} {\mathrm e}^{2 \lambda x} \left (g \relax (x )-f \relax (x )\right )=0} \end {gather*}

Solution by Maple

dsolve(diff(y(x),x)=f(x)*y(x)^2-a*exp(lambda*x)*g(x)*y(x)+a*lambda*exp(lambda*x)+a^2*exp(2*lambda*x)*(g(x)-f(x)),y(x), singsol=all)
