Question

It's a puzzle
Our school math teacher gave
She told a = b
And then she solved it and 2= 1 ans came
And she asked how is it possible


PLEASE TELL ME HOW IS THIS POSSIBLE​

Answer 1

Answer:

a=b .................(1)

we multiply a in both

a²=ab

also multiply -b²

a²-b²=ab -b²

(a-b)(a+b)=b(a-b)

(a+b)=b

from equation 1

a=b

(b+b)=b

2b=b

then

2=1
