2 is an exponent. it is not a variable.

a = b

a² = ab . . . . . . . . . . . . . . . . . .a² = aa = ab, since a = b

a² - b² = ab - b² . . . . . . . . . . .subtract b² from both sides

(a - b)(a + b) = b(a - b) . . . . .factor a² - b² and ab - b²

a + b = b . . . . . . . . . . . . . . . . .cancel (a - b) from both sides

incidentally, a =0, b = 0

i do feel as tho answering this was a little of a waste of time since this is not a real equation and that the reason you asked this question was something like resentment.

When you defined that a=b you disproved yourself because
(a-b)=0 so now you have 0*(a+b)=b*0 so the equation equals 0=0
Your not going to disprove alebgra so just give up.

2 = 2

2 = 2 + na

2 = 2 - na

2 = 2 + nb

2 = 2 - nb

2 = 2 + nab

2 = 2 - nab

2 = 2 + n(a - b)

2 = 2 + n(a + b)

2 = 2 - n(a + b)

2 = 2 - n(a - b)

2 = 1, but you made a mistake at step #4 where you divided by (a-b). You are dividing by zero at this step which is incorrect leading to a fallacious answer.

if a=b
then a2=b2
then a2-b2=0 ;o)
so
0 = a2-b2=ab-b2
0=b(a-b)
gives a=0 and b=0 my man..!

2=2 but a+b doesn't = b it equals 2b because a=b so it's b+b=2b.
