Need help!

I don’t know if any of my readers can help me out with these one.

Let u,v be algebraic over F. u is separable and v is inseparable over F. Prove that F(u+v) = F(u,v) moreover, if u,v != 0, F(u,v)=F(uv).

Man, I was working on this for like 2 1/2 hours and no idea how to start. My general idea was to show that somehow [F(u,v) : F (u+v) ] =1. So far my ideas don’t even hit it!!

Arghh….help help help!!
