Hey JG, don't know why others aren't commenting about your problem but for me it is a bit awkwardly posed. This is what I would consider well-posed:

[tex]\text{DE:}\quad Au_{xx}+Au_{yy}-B(x)u_x=0\quad 0\le x \le L[/tex]

[tex]\text{BC:}\quad u_x(0,t)=0\quad u_x(L,t)=0[/tex]

[tex]\text{IC:}\quad u(x,0)=f(x)\quad u_t(x,0)=g(x)[/tex]

Now saying that's yours but if the problem were this, then I'd use separation of variables and proceed.
