    I told you that formula is wrong.
    If that is exactly what your book says then it wrong and you should burn it to death.

    a=5,b=-8h,c=b^2
    supposely i should take the coefficient right?

    <br />
4h^2-8rh+b^2=0<br />
    a = 4, b = -8 , c = 1

    \frac{-b\pm \sqrt{b^2-4ac}}{2a}

    \frac{8\pm \sqrt{64 - 16}}{8}

    Am i right? pls correct me if i am wrong. thanks guys

    If true burning to death is a too merciful fate for it. It should be extinguished
    while still alive, be disembowelled, have its entrails burnt before its eyes, the
    be hung on London Bridge until it smells so badly that the Aldermen demand
    that it be taken down and disposed of somewhere where nobody will notice
    (Utah?).

    Wrong.
    For the third time the formula is,
    \frac{-b\pm\sqrt{b^2-4ac}}{2a}

    a = 4, b = -8 , c = 1

    -(-8)\pm \sqrt \frac{(-8)^2 - 4(4)(1)}{2(4)}

    8\pm \sqrt \frac{64 - 16}{8}

    Am i right? pls correct me if i am wrong. thanks guys
    I expect ImPerfectHacker is composing a blistering reply to this
    so I will just say, people have told you repeatedly that this is not the
    quadratic formula.

    It was a LaTeX error. The user does not know how to type that correctly. I presume it is because of the double bracket. I know that because I am speaking with the user through MSN.

    CaptainBlack I want you to know that I like women but, you know, I'm kinda getting turned on by this... However, you forgot about smearing it in honey and burying it in a mound of fire ants, so don't expect any dates.
