CAS Maple gives this as type [_linear]

\[ \boxed {y^{\prime } x^{2}+x \left (x +2\right ) y=x \left (1-{\mathrm e}^{-2 x}\right )-2} \]

Solution by Maple

Time used: 0.0 (sec). Leaf size: 31

dsolve(x^2*diff(y(x),x)+x*(2+x)*y(x) = x*(1-exp(-2*x))-2,y(x), singsol=all)
 

\[ y \left (x \right ) = \frac {{\mathrm e}^{-x} c_{1}}{x^{2}}+\frac {x \,{\mathrm e}^{-2 x}+{\mathrm e}^{-2 x}+x -3}{x^{2}} \]

Solution by Mathematica
