    I don't feel like writing it out, but y is the 26th power polynomial of x.

    x^26 - ..... + abcdefghijklmnopqrstuvwxyz

    Were you given this as an assignment, or just making busy work for us?

        I saw this somewhere recently, but I can't remember where. I think the answer is 0, but I have no idea why.

          Yes. y = 0 because (x-x) = 0 and should require no further explanation from here.

            well somewhere in there you have (x-x) so yeah, 0.

                        You have answered one of my questions. This is Qwizzle number 74(ish).

                        I recognised the problem, but it has been a long, long time so the brain ached for a while.

                        Of course, y=0. That sytnax is code for (x-all values).

                          Ahh. I see the slip. Sorry. In my defense, that's ridiculous and stupid. LOL.

                          One does not normally do "x-x", one assumes that x and y are variables and a-z are constants. *shrug*

                            Are you still battling on, or have you given up on it? I have to admit to a distinct lack of enthusiasm after the first 60-odd, and needing more hints thereafter, but having got this far I plan to finish it at somepoint soon.

                              I never thought I'd say this, but this was my exactly my reaction too...
