Proof for 1=2

solution:

a=b

a^2=ab

(a^2)-(b^2)=ab-(b^2)

(a+b)(a-b)=b(a-b) => a=b .....(1)

a+b=b

from equation (1)

b+b=b

1+1=1

2=1!!!

Warning : Opps if a=b then (a+b) *0 = b *0 so 0/0

solution:

a=b

a^2=ab

(a^2)-(b^2)=ab-(b^2)

(a+b)(a-b)=b(a-b) => a=b .....(1)

a+b=b

from equation (1)

b+b=b

1+1=1

2=1!!!

Warning : Opps if a=b then (a+b) *0 = b *0 so 0/0
