(x - x)(x + x) = x(x - x)

Those aren't equal.
It reads 2x = 0 which only would be true if x=0

I was going to make a comment, but my thoughts arent straight enough for it to make sense on a message board. The only thing that comes to might that DOES make sense is F.O.I.L.

(x -x)(x + x) is the same thing as 0(2x) which is equal to x(0) as both end up as 0. 0 = 0. It's a joke problem and isn't meant to be taken seriously as it's impossible to divide by zero.

I've seen this a few years ago.
This is simply called a paradox but there's still something wrong with it. In maths, the parentheses always have the priority so you have to solve them first before divinding (x-x)'s. And since x-x = 0 it's going to be 0 = 0
