\[ \left \{ y \left ( x \right ) = \left ( -{\frac {1}{a+2}{{\rm e}^{-{\frac {{x}^{2} \left ( a+2 \right ) }{2}}}}}+{\it \_C1} \right ) {{\rm e}^{{\frac {a{x}^{2}}{2}}}} \right \} \] Mathematica raw input
DSolve[y'[x] == x*(E^(-x^2) + a*y[x]),y[x],x]
Mathematica raw output
{{y[x] -> (E^((a*x^2)/2)*(-E^(-((2 + a)*x^2)/2) + (2 + a)*C[1]))/(2 + a)}}
Maple raw input
dsolve(diff(y(x),x) = x*(exp(-x^2)+a*y(x)), y(x),'implicit')
Maple raw output
y(x) = (-1/(a+2)*exp(-1/2*x^2*(a+2))+_C1)*exp(1/2*a*x^2)
