Find the mistake in the given equation when it is given that a=b adding a on both sides, it becomes a^2=ab....... Now subtracting b^2 from both sides it becomes a^2-b^2=ab-b^2........Now factorising it becomes (a+b)(a-b)=b(a-b)...........Cancel a-b on both sides, it becomes a+b=b.... As a=b (given) .......a+a=a.......2à=a........which proves 2=1 !!!!!!
