Question

Is x-2 is a factor of x^2- 2

Answer 1

Answer:

x-2=

(2)^2-2

=4-2=2

therefore its is not a factor

Answer 2

Answer:

If x - 2 is a factor of x^2 - 2 then it will leave 0 as the remainder.

x - 2 = 0

x = 2

x^2 - 2

= 2^2 - 2

= 4 - 2

= 2

As 2 is remained so it is not x - 2 is not a factor of x^2 - 2
