(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Given y1=x^2 and y2=1 are two solutions of the DE

y"=(x/y)y'

Are the functions -y1 and y1 and y2 also the solutions of the equation?If not why?

2. Relevant equations

3. The attempt at a solution

I cannot see how to proceed.However,I can see that it is a non-linear DE of

2nd degree where we cannot simply sum the solutions to have another solution...

That might explain the case that y1+y2 is not a solution...

what about the first case,i.e -y1?
