How can you prove something that is not true?

Re: A lovely question
hi Exist,
Welcome to the forum.
I need another proof first; then, it's easy!
Let a = b
then
Factorise:
Cancel the common factor (a-b)
Now to tackle your question:
Let a = b = 1 then
1 + 1 = 1
But 1 + 1 = 2 => 1 = 2
Now add 1 to each side
1 + 1 = 2 + 1 = 3 QED. 
He then went on to prove that black = white and got run over crossing the road on a black/white crossing!

Re: A lovely question
I knew that. A false result can only be obtained by incorrect working.
