1. Where is false with this?
Let us suppose a and b are any two positive
integers so that a = b
Or, a2 = ab [Multiplying both sides by a]
Or, a2–b2 = ab–b2 [Subtracting b2 from each side]
Or, (a-b)(a + b) = b(a-b) [Factorized]
Or, a+b=b [ Cancelled equal terms on both sides]
Or, 2b=b [ Replacing a by b]
Therefore, 2=1 [Amazing Answer!]
