DSolve[(a + b*x)*y[x] + y''[x] == 0,y[x],x]
Mathematica raw output
{{y[x] -> AiryAi[-((a + b*x)/(-b)^(2/3))]*C[1] + AiryBi[-((a + b*x)/(-b)^(2/3))]
*C[2]}}
Maple raw input
dsolve(diff(diff(y(x),x),x)+(b*x+a)*y(x) = 0, y(x))
Maple raw output
[y(x) = _C1*AiryAi(-1/b^(2/3)*(b*x+a))+_C2*AiryBi(-1/b^(2/3)*(b*x+a))]
