Hey Math people, this ones for you!

The person I work with does a lot of math riddles and got me on this one;

Expaned

(x-a)(x-b)(x-c)…all the way to (x-z)

Try not to post the answer, it gives away the fun,

In a day or so I will put the second part of it up.

alright for thoose who got the answer, try doing the equation with out the (x-x). I have been searching / writting a program that would do it for me, I am to lazy to sit down and do it by hand…

Good Luck
