1. ## Question about deleting a value of x.

Hi

The Problem :

I know how to solve the problem, but my question is why $x \neq 0$. ?

What is the reason ?
Is there a theoretically answer? knowing that it has been solved using Reduction of Order Method.

2. Because the homogeneous solution is where x = 0...

The problem also becomes first-order if x = 0.
