For the RHS of the equation in the second one you can see that dividing by the differential of the ‘bracket’ means lambda / lambda so it just equals 1. So that helps simplify the equation instead of ending up with 1 / lambda. If you mean for the other terms, always split up the dy / dx bit because then it becomes like an integral.
