    2=1, is this valid?

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

    No, because a-b equals zero, therefore you are dividing by zero which is a no-no. Its like saying zero times three equals zero times four, cancel the zeroes and you get three equals four.

    Where did you get 2=1? As far as I can tell, a and b both equal 0

    This thread gets two thumbs down.
