A differential equation is homogeneous only if the term d(x) in your case is equal to zero, i.e. there is no term which does not include a function of the dependent variable.
Your previous videos were actually on homogeneous coefficients of differential equations, which is something completely different.

@kkc1648 damn straight. I especially hate those who always say, i would assume you knew blah blah blah.

unbelievable video!

@sickpee Get "Ordinary Differential Equations" by Morris Tenenbaum and Harry Pollard. It's only $15 on Amazon. You need the Wronskian for 3rd order and greater. Using the method of variation of parameters. In reality 4th orders are about the most tedious a professor would assign you. In real life problems people would plug it into some computer algebra system instead of spending so much time with the risk of human error.

@SirDigby01 There are too few true polymaths any more. I mainly come here for the pure math videos, but the broad scope of stuff he does is impressive.
you rock
