Explanation: How did they get from
x + 2 = x - 2
to
(x+2)(x-2)=0?
That’s not a valid step.
It’s also necessary for x to be either 2 or -2 for the equation to have a value of zero.
Almost everything is wrong in his answer.
The correct answer is, it’s unsolvable.
X + 2 = X - 2
X - X = - 2 - 2
0 = - 4
The real correct answer is that it only works mod 4
Only the first step is wrong.
