I'm stuck on this problem. I need to get the most general solution to:(adsbygoogle = window.adsbygoogle || []).push({});

Uxx - Uy - Ux =0

without using separation of variables.

I have no clue how to use the method of characteristics for second order PDE's. My prof hasn't taught us anything about that. All we learned how to do is factor operators.

Help would be appreciated!
