Flawed Proof If a = b then a^2-ab = 0. Canceling a zero factor is not allowed. e.g. 0*5 = 0*2 if you divide by 0 you obtain 5= 2. You can get anything you want. Robert Pour Reply

If a = b then a^2-ab = 0.

Canceling a zero factor is not allowed.

e.g. 0*5 = 0*2 if you divide by 0 you obtain 5= 2. You can get anything you want.
