Question

x2 - x2 = x2 - x2. prove that 1=2

Answer 1

your answer

X^2-X^2=X^2-X^2 (True)

Taking X common from L.H.S and applying the formula A^2-B^2= (A+B) (A-B) we get,

X(X-X) = (X+X) (X-X)

Now just to puzzle you out many cancel (X-X) from sides which cannot be done mathematically as X-X will always be Zero. And anything divided by Zero will be termed as Indefinite. So mathematically this question stands incorrect and cannot be proved.

Answer 2
