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

Update : This puzzle is now solved

I consider this to be one of the more silly puzzle questions :p

Question

What is the value of this multiplication :

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

Answer

As rightly pointed out by Ajay and Kalpana, the answer is "zero".

The reason being, x-x = 0

    (x-a)(x-b).....(x-u)(x-x)(x-y)(x-z) = 0

    Since in the above multipliaction (x-x) = 0

    Substitute it .. Ans would be "0"
