    Post Symplify

    Hi!
    I would like to know if there is any shortcut to the given statement:

    (a-x)(b-x).......(z-x)

    Solving it by opening all the parentheses is not, according to me, a very sensible thing to do here.
    Any other rule which can be applied to simplify it?

    Thanks a Lot!

    Would (x-x) be one of the factors?

    Re: Symplify

    Ummm.....Well....how??
    I'm not really understanding this.
    I've already gone on Google and searched this, all the answers say is that (x -x) is the factor, but I don't really
    understand how....

    Look at the pattern:
    (a-x) times, (b-x) times, (c-x) times, until we get to (z-x) times.

    Okay, so what?
    (I'm sorry if you're if you feel I'm annoying you but this is not from my school course, just a question which popped out from some higher-class book, and it really intrigues me)

    Anyways, thanks

    The answer is 0. That because x-x=0 so 0 times the rest is 0.

    Uh-Oh....
    I can understand that but I don't understand why the factor is (x-x).

    Re: Symplify

    Go through the alphabet. Surely you'll get to x if you go a, b, c, d, ...

    Of course, this is assuming that you're using the symbol x from the alphabet to represent the same thing as the variable x in the statement, which it is quite likely you are not... But if that wasn't the case it would not be so easy to solve.
