    –2=–2
    =>1–3=4–6
    =>1²–2×1×3/2=2²–2×2×3/2
    =>1²–2×1×3/2+(3/2)²=2²–2×2×3/2+(3/2)²
    =>(1–3/2)²sad2–3/2)²
    =>1–3/2=2–3/2
    =>1=2

      I asked my friend, who is a mathematician.
      This was his reply, "Error is in line 5.  There's a sad face there.  It should be a happy face."
      I don't know if he was kidding or not.

        The problem is not there. But how the notice is not bound by anything that has been hardened in people's minds.

    It is because the two sides of the equation are not equal.

      My friend said your comment was useless... lol... although he said "kind of" probably to soften the blow.

        Good for your friend, so nice of you to share that.

        My comment was correct, though.

          lol. Im sure he didn't mean it unkindly... he's Canadian. They don't know how to be unkind. Im sure it was just an observation.

            But, I'm sure you did, or else you wouldn't have even posted it.

              Yes, I was poking you a bit. I doubt you burst into tears over it, or did you? If so, I'm sorry, if not... then wasn't that fun?

                No, I don't burst into tears from your insults and gossiping on these forums, I actually feel very sorry for you.

                    Considering one of your old friends has not been around, it is nice to see you found a new one.

    Oh, ok... ignore the last post... here is the actual deal.

    "My actual solution would be to replace line 6 with
    =>(-1/2)^2 = (1/2)^2
    =>1/4 = 1/4"

    Now tell me it's right so I can move on!

    CHRIS57posted 4 years ago

    line 5: (1-3/2)² = (2-3/2)² correct
    => (-0,5)² = (+0,5)²
    => 0,25 = 0,25
    line 6 game over :-)
    however what is possible:
    1x(-0,5)²= 1x(0,5)²
    => 1 = (0,5)²/(-0,5)²
    => 1 = (0,5/-0,5)²
    => 1 = (-1)²

    Last line; one does not equal two.  Unless it's not mathematics but some sort of heart-felt philosophy.  Looks like mathematics to me, but I'm no Einstein.

    replace line 5 with:

    =>|1–3/2 |= |2–3/2| or

    =>-|1–3/2| = -|2–3/2|
    When you took the sqr root of each side in the preceeding step to produce this one, you assigned a negative value to one side and a positive to the other.  As that function has two possible answers, you must specify which one is applicable.

    Barack Obama = man
    Nasrullah Idris = man

    Barack Obama = 2
    Nasrullah Idris = 1
    man = x

    so
    2 = 1

      Pshaw. We all know he's actually one of the reptilian overlords who will enslave us and charter us to their home planet to mine gold for them until we die.

      It's true! I saw an image of him on my old TV and part of his skin was green, so it must be true!

      That's not math. That's bull shit like the anything equals anything logical fallacy....which is essentially what you're using if you randomly equal anything to a mathmatical symbol and then treat it like math.

    The mistake begins at line 5.

        huh what do you mean? I can't figure out if that's a complement or an insult?

          Sam... he was the OP... I guess I feel like we need him to put an end to this for us.

    For this, we are not talking a numeric value, but the status of numbers.
