Step-by-step explanation:

It happened due to mistake.

Answer 2

Answer:

The following is a "proof" that one equals zero:

Consider two non-zero numbers x and y such that

x = y.

Then x2 = xy.

Subtract the same thing from both sides:

x2 - y2 = xy - y2.

Dividing by (x-y), obtain

x + y = y.

Since x = y, we see that

2 y = y.

Thus 2 = 1, since we started with y nonzero.

Subtracting 1 from both sides,

1 = 0.
