\[ x y^{(3)}(x) (a x+b)+(\alpha x+\beta ) y''(x)-f(x)+x y'(x)+y(x)=0 \]

Mathematica : cpu = 6.78745 (sec), leaf count = 56731

DSolve[-f[x] + y[x] + x*Derivative[1][y][x] + (beta + alpha*x)*Derivative[2][y][x] + x*(b + a*x)*Derivative[3][y][x] == 0,y[x],x]

Maple : cpu = 1.073 (sec), leaf count = 1212

dsolve((a*x+b)*x*diff(diff(diff(y(x),x),x),x)+(alpha*x+beta)*diff(diff(y(x),x),x)+x*diff(y(x),x)+y(x)-f(x)=0,y(x))
