Question

how is it possible ​

Answer 1

Answer:

there is a fault

in the third step, how you can subtract the same number from it

Answer 2

This is not possible but possible only a process .

2 = 2

squaring both sides

2^2 = 2^2

subtract both sides by 2^2

2^2 - 2^2 = 2^2 - 2^2

In LHS using the formula A^2 - B^2 = (A - B)(A + B)

( 2 - 2 )(2+2) = 4 - 4

(2 - 2)(2 + 2) = 2(2 - 2)

Here (2 - 2) cancel ,because exist in both sides , so we get

(2 +2) = 2

4 = 2

Now subtract both sides by 2 ,we get

4 - 2 = 2 - 2

2 = 0 proved
