let a=b
Multiplying both sides by b
ab=b^2
substracting a^2 from both sides
ab-a^2=b^2-a^2
a(b-a)=(b+a)(b-a)
Dividing both sides by b-a
a=b+a
a=2a
1=2
This identity cannot be possible
Is anything wrong with my steps..Figure out

"Dividing both sides by b-a" is dividing by zero, the cardinal sin of mathematics.

B-A = 0, and at one point, you are dividing both sides by 0 and not possible.

Dividing both sides by b-a is dividing by zero.

when you divide b-a it equals 0, and when you divide a number by 0 it equals infinity. and all those that say a number cannot be divided by zero, attend your basic schooling again. don't harm our maths world

You cannot divide by (b-a). Division by zero is not possible. That's the wrong step.
haha, I like the term "cardinal sin". Just so.

a-b=0 u canot divide by it

a=b and so b-a=0...
Dividing by zero is not possible...
You need to attend your basic schooling again my dear.

hey friend u assumed a=b ok.in ur step a=a+b there is also a possibility that
a=a+b;
a-a=b;
b=0
a=0
so its possible for a=0 b=0

a=b+a
subtract a from both sides
0=b.

you can't divide by b-a
