what is answer for this series?

Question

(x-a)*(x-b)*(x-c)...............................................*(x-z)= ?

Answer 1

Hovering over your question I see it is:
(x-a) * (x-b) * (x-c) * .... * (x-z).

This is a trick question. Since it includes (x-x) which is zero, and this is a product, the answer will be ZERO! You almost had me trying to multiply out the polynomial... :-)

Answer 2

(x^2 -ax - bx + ab) * (x-c) =
x^3 - ax^2 - bx^2 - cx^2 + abx + acx + bcx - abc =
x^3 - (a + b + c) x^2 + (ab + ac + bc) x - abc

Answer 3

this is more like a product....
and the answer is an infinite product
