    What did people get for two last multiple choices? I got d and b. The penultimate one was about max of ax + by when x^2 + y^2 <= 1 and the last was about the number of distinct prime factors and the last digit.

    I think the idea was that if x^2 + 1 is a factor then subbing in x^2=-1 should give you 0, which only works if n is even

    There's probably something I didn't think about that makes that wrong though

    It was no values of n
    it works for n equals to 2. difference of squares.

    I swear like 2 or 3 of those were false not just 1 lol

    can't remember which one i chose

    and for the penultimate i guessed as sqrt(a^2 + b^2)

    aww **** I thought it was x^2-1 so split it into (x+1)(x-1)
