What are the limitations of ohm's laws?

If 1 & -1 are the zeroes of the polynomial p(x)=Lx^4+Mx^3+Nx^2+Rx+P=0, prove that L+M+P=M+R=0.    [JEE mains 2014, AIEEE 2006, IIT 1998]

Potential Difference=12V
Now, the question is just confusing u.
Current is uniform throught the circuit, as i know from NCERT books.
So, I=V/R=12/3=4 ohms
