  1. That was the bit I didn't like either!
  2. 'You could take any quartic
    Not a quartic expression. So what was written was nonsense and therefore neither proves nor disproves anything.
    That is why more needed to be said..
  3. Who said it was a quartic expression? I wasn't trying to prove or disprove anything. It was not a formal argument. It was just a hint.

    What you do not write in a solution does not need to be written well.

    Going back to the discussion of Q5, are they saying that, as m and n are integers and m is a factor of a quartic in n, then m must be a polynomial function of n? Perhaps there is a theorem that says so - I don't know it and don't think it reasonable to expect candidates to know it. Once this is assumed, you can say that m + 1 must be a polynomial of the same order, so both must be quadratics.
