### Evidence that two is not equal to one. 2 = 1 .

Obviously two is not equal to one, the show that says otherwise has a hidden error between the lines 4 and 5.

Line 4 - Factoring :

to ( b - a) = (a + b ) ( b - a)

Line 5 - And simplifying the term ( b - a) :

a = a + b

By simplifying the term ( b -a) we do we are divide both sides of equality ( b -a) , or what is the same, divide by zero , invalid operation.

The math does not lie.
