How to Proved that 1=2 ? [Solved]
Hello guys, how are u ? Mathematics is our live . We can't get a step without it . Now know more about it with fun . Today i'm going to prove a interesting fact i.e. Proof. of 1=2 Which is called ' Fallacy ' In mathematical Language . If you want to read it in Bengali Please Click Here We will prove it in three different way Proof : 1 Let, x = y [where, x & y both integers] or, xy = y² [Multiplication by 'y' ] or, xy-x² = y²-x² [Subtracting x² from both side] or, x²-xy = x²-y² [Multiplication by (-) ] or, x (x-y) = (x+y) (x-y) or, x = x+y or, x = x+x [as we put, x=y] or , x = 2x or, 1 = 2 Therefore , 1=2 Proof: 2 Let, a = b [where, a & b both integers] or , a ² = ab [Multiplication by 'a' ] or , a ² + a ² = a ² + ab [adding a² from both side] or , 2a ² = a ² + ab or , 2a ² - 2ab = a ² + ab - 2ab [Subtracting 2ab from both side] or , 2a ² - 2ab = a ² - a
