    I cannot figure which method to solve it with (linear, exact, homo, ect) x(dy/dx)=y + sqrt(x^2 + y^2)

    \[x \frac{ dy }{ dx }=y + \sqrt( x^2-y^2) \]

    homogenous \(y=ux\) you have to change it; to seperable

    \[\large x\frac{dy}{dx}=y+\sqrt{x^2+y^2}\] correct?

    so, its homogeous \(y=ux\) \[\frac{dy}{dx}=v+x\frac{dv}{dx}\] are you able to start it?
