Simplification of nonlinear differential equation
Given this nonlinear differential equation
$$
[(1+epsilon y) y']'+ 2xy'= 0, 0 < x < infty,
$$
why we can write it like the following?
$$
[(1+epsilon y) (1+ epsilon y)' ]' + 2x(1+epsilon y)'= 0 , 0 < x < infty
$$

Note that $(1+epsilon y)'=epsilon y'$. So if $epsilon neq 0$, we can cancel out $epsilon$ from second equation to get back the first one.
