Maths fail

a = b
a^2  = ab
a^2-b^2 = ab - b^2
(a+b)(a-b)  = b(a-b)
a+b = b
2b = b
2 = 1

Houston we have a problem.

 I divided by zero!

    everything fails when zero comes in mind...zero is surely a magical number

    "a=b
    a^2= ab

    uhm? "

    You are multiplying with a on both sides.

    @Layman Researcher: Yes, that's how equations work.
    Still, you can't have one single answer when you had a quadratic equation in some point.

    It's something with how they factor which is incorrect. I remember this problem in Adv Algebra.

    a = b
    a^2 = ab
    a^2-b^2 = ab - b^2
    (a+b)(a-b) = b(a-b) --- aa-ab+ba-bb = ba-bb
    a+b = b
    2b = b
    2 = 1

    yes, it's the division by zero that breaks the algebra.

    My math teacher fooled our entire class for over half an hour, before he told us what the 'trick' to this equation was. :D
