Hint: There's a division with zero

dividing by a-b is wrong, as it's actually zero

Never seen it before and happy I immediately figured it out :)
(a + b)(a - b) = b(a - b)
evolves to
a^2 - ab + ab - b^2 = ab - b^2
which is
a^2 = ab
No way you got a + b = b. You got the invalid result by dividing by 0

(a+b)(a-b) = b(a-b) since here ok but,
then isn't allowed to divide the (a-b) with the other (a-b)

Lemme help some people:

a^2 = a*a

a^2 = a*a

a^2 - a^2 = a*a - a^2

(a+a)(a-a) = a(a-a)

a+a = a

a+a = a

2a = a

2 = 1

For anyone who has a hard time with algebra,try plugging in some real numbers. Start with a=1, if you like. If you can't figure it out by the third line...

@-vim- but in the fourth line you are multiplying a to 0. a(a-a)

(a-b) = 0 therefore you can't divide by it as you can't divide by zero.
