If I prove 1=2, can you prove me wrong?

[Janaki]

every thing is good except for the canceling common factor thing. we cannot just cancel the common factor out what were are actually doing here is dividing both sides by common factor a2-ab, now division is only good when we are not dividing by zero, but here a2-ab is o cuz we let a=b, for this reason we can't go any further so the problem is correct only till 2(a2-ab)=1( a2-ab).

As a=b replace b with a at last step then a2-a2 both sides ante 1*0=2*0
