A mammoth product

What is the value of the product of 26 algebraical expressions (x-a)(x-b)(x-c)...........upto (x-z)where a, b, c, ............ z represent the english alphabets?

Answer:

The answer is more trivial than you think, but more harder than you imagine! Solution: The answer is, just a moment, hold your breath, 0. Youwonder how? Because out of 26 algebraical expressions, (x-x) is also one among them whose vaule is 0. Hence the product is 0.
