Question

x³-x³=x³-x³
(x-x)(x²+x.x+x²)=x[x²-x²]
(x-x)X3x²=x(x-x)(x+x)
3x²=xX2x
3x²=2x²
3=2

find the mistake​

Answer 1

Answer:

It's wrong. The reason for it is as follows : Let's under stand it by an example, say x= 7. So by the given equation 7(7–7) = (7–7)(7+7).

Answer 2

You have written x3 - x3 = x3-x3
Instead of that you have to write x3-x3=x3+x3
