\[[y \left (x \right ) = \textit {\_C1} \left (x^{2}+1\right )^{b} {\mathrm e}^{a \arctan \left (x \right )}]\] Mathematica raw input
DSolve[(1 + x^2)*y'[x] == (a + 2*b*x)*y[x],y[x],x]
Mathematica raw output
{{y[x] -> E^(a*ArcTan[x])*(1 + x^2)^b*C[1]}}
Maple raw input
dsolve((x^2+1)*diff(y(x),x) = (2*b*x+a)*y(x), y(x))
Maple raw output
[y(x) = _C1*(x^2+1)^b*exp(a*arctan(x))]
