In this video we find the general solution to the second order differential homogeneous equation y" - y = 0 by first finding the characteristic equation which allows allows us to solve for the roots.

single root general solution is y= C1e(rx)+C2(x)e(rx) ??

it's weird to see people confusing this with the harmonic equation in this comment section lol
like i know this is youtube comments but come on man pay more attention

Thank you for uploading. then how can I calculate such as y' - y = 5?

Solve the differential equation :
y' + y = 1

This video is completely wrong. The roots are different and the answer should be in the form of cos and sin

a real mathematician on quora had written that if u=y' or u=dy/dx
then y''=du/dx
so dx=du/y'' and
dx=dy/u
so this leads to y''=u*du/dy and i get as new equation
y+u*du/dy=0
this integrates to
y^2=-u^2/2+c1 but now i get stuck. can anyone help me or tell me
the link to a solution?

nice bullshit. single root is y(x) = c1e^rx + c2xe^rx
