$$a{y}^{\prime }(x)|y^{\prime }(x)|+b{y}^{\prime }(x)+cy(x)+y^{″}(x)=0$$ ✗ Mathematica : cpu = 7.79432 (sec), leaf count = 0 , could not solve

DSolve[c*y[x] + b*Derivative[1][y][x] + a*Abs[Derivative[1][y][x]]*Derivative[1][y][x] + Derivative[2][y][x] == 0, y[x], x]

✓ Maple : cpu = 6.476 (sec), leaf count = 59
