# 2=1 is false, prove that it's false!

**Algebra**Level 1

Let a=1 and b=1 Hence, a=b Multiplying both sides with a, we get:- a^2 = ab subtracting b^2 from both sides, we get:- a^2 - b^2 = ab-b^2 and.... (a + b)(a - b) = b(a -b) So, (a -b) gets cancelled on both sides, and we are left with a + b = b Re-substituting, we get, 1 + 1 = 1 2=1 We all know that it's not true! So post the mistake in this solving..........or you must believe that it's true! THIS PROBLEM IS JUST FREE POINTS FOR YOU!!!!
