    Solve a dilemma

    Pls solve a following dilemma

    a=b
    a^2=ab Multiplying both sides by a
    a^2-b^2=ab-b^2 Subtracting b^2 from both sides
    (a+b)(a-b)=b(a-b)
    (a+b)=b
    b+b=b
    2b=b
    2=1

    This is a cliche done to death. Look close. a=b, doesn't it?. Therefore, you have division by 0 and the proof is bad.
