$$h(y(x))y^{\prime }(x{)}^2+j(y(x))y^{\prime }(x)+k(y(x))+y^{″}(x)=0$$ ✗ Mathematica : cpu = 52.3241 (sec), leaf count = 0 , could not solve

DSolve[k[y[x]] + j[y[x]]*Derivative[1][y][x] + h[y[x]]*Derivative[1][y][x]^2 + Derivative[2][y][x] == 0, y[x], x]

✓ Maple : cpu = 0.563 (sec), leaf count = 59
