A minor alternative that can make the calculus a little easier:

Hi eigenguy,

...how do you get alternative text other "Hidden Text"?

After "[hide", type "=", followed immediately by the text of your choice and the closing bracket ']'.

Here...I'll try it with "minor alternative" in the hide box:

Just click on 'Quote' in the bottom right-hand corner of my post to see what I did.

Thanks!

It's been a while since been in a forum. It's embarrassing that I'd forgotten about the quote trick!

Hi;

Did you see my completely original answer. I trust that JFF would like it.

Can I remind everyone that the title of this thread is

Easy puzzle challenge. Therefore if your solution is messy and complicated, youre on the wrong tack.

Yet, that's harder than what's shown in #31

I guess DeMoivre's and Vieta's is a bit of an overkill but maths is all about solving problems in different ways.

Yeah, proofs of even simple results can sometimes be a bit messy.

Still true today as it was then. Anyway, how about another problem.

You'd better add "monic" to your description of f, or else it can't be proved, since for any a, af(x) is another polynomial with the same roots.
