Everything is a lie. And it can be proved with a bit of simple algebra;
Let's suppose that a = b. Therefore, a² = ab
Then divide both sides by (a² - ab) and you get 2 = 1.
Amazing eh?
Let's suppose that a = b. Therefore, a² = ab
+ a² to each side
a² + a² = ab + a²-2ab from each side
2a² - 2ab = a² - abTake a common factor of 2
2(a² - ab) = a² - abThen divide both sides by (a² - ab) and you get 2 = 1.
Amazing eh?
