Do you think this math equation is correct?

Is it possible to 2 = 1??
Of course not. Here i'll give you the solution

Where is the mistake??  .
 The mistake is in line 7.

Since a = b ------- therefore (a^2 - ab) should be 0.
So,

2(a^2 - ab) = 1(a^2 - ab)

 2(0) = 1(0) 

0 = 0

PROVEN!

hehehe....do you get it??
