x^2 —— = x x
Proof?
If you’re saying two variables are equal, then x=x is valid. The only issue with this is it doesn’t indicate the restriction at x=0. This is a “hole” in the function since anything/0 is undefined. For all other cases the equation holds true.
So x = x if x ≠ 0 and x ≠ x ≠ 0 if x = 0, got it.
