x-x=0 so whole is zero

X= (x-1)……(x-100)…..(x-a)……(x-z)
here ,
x can be a whole number or rational or irrational or even unreal number ,,  and  ,, the same can be said for the ‘ a’, ‘ b ‘, ‘ c ‘,’ d ‘  … ‘ z ‘ .  as I am not bound by any type of restriction to think of a particular group of  values of x.
since,         X= (x-1)……(x-100)…..(x-a)……(x-z)
=>         X={  (x-1)  .  (x-2)  .  … . (x-100) . …}{ (x-a) . (x-b) . … . ( x-z ) }
=>         X={ A } . { B }
Case1:     for A,      1) if x is Whole no. , then A=0 .  2) x is Real but not Whole no. , then  A is not 0 .
Case2:     for B,      1) if x= Real or Unreal ,but  x= a or b or … or z   , then B=0   2) x and a,b,c…z are nowhere near each other in the family(say x is Whole or a is Rational etc) or in their family set( say x and abc..z are rational but way different in values) then, B is not 0.
from above we can conclude that,
X=0 ,,,,  for Case1.1) and Case2.1)  (atleast)
but not  X=0 many possiblities.
