1) a=b 2) ab=a^2 3) abb^2=a^2b^2 4) b(ab)=(a+b)(ab) 5) b= a+b
Reminder the first step where b = 2b So,
1=2.
In this case in my opinion the wrong step is that in the third, because you can´t subtract b^2 from both sides.

Best ResponseYou've already chosen the best response.2\[\rm b(a  b) = (a + b)(a  b)\]Since (a  b) = 0,\[\rm 0b = 0(a + b)\]

Best ResponseYou've already chosen the best response.2But what this thing shows is that it's divided both sides by 0.
