Proof that 2 = 1
2 = 1 Proof
Let us use basic algebraic proofs. We begin by using X and Y as any rational value.Let X and Y be equal values: | X = Y | |
---|---|---|
Multiply boths sides by X: | X^{2} = XY | |
Subtract boths sides with Y^{2}: | X^{2} - Y^{2} = XY - Y^{2} | |
Factor each side: | (X - Y)(X + Y) = Y(X - Y) | |
Divide by (X - Y) | X + Y = Y | |
Since X = Y, substitute Y with X: | X + X = X | |
Simplify | 2X = X | |
Divide by X | 2 = 1 |
