    Dividing by 0 is indeterminate form or meaningless. Hence 4x-8 can not be 0, or x cant be 2.

    Let a/0=c. Hence c.0=a We can not assign a definite value to c for which c.0=a. Hence, dividing by 0 in meaningless.

    @SMISHRA The excluded value is what makes the denominator zero: 4x - 8 = 0 4x = 8 x = 8/4 x = 2
