    1. The problem statement, all variables and given/known data
    Given real numbers a,b,c,d,e>1 prove that
    a^2/(c-1) + b^2/(d-1) +c^2/(e-1) +d^2/(a-1) +e^2/(b-1) =>20

    3. The attempt at a solution
    I am not sure how to do this. Although I think using properties of polynomial equations would be very useful
