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.

Thus,
$\displaystyle 4h^2-8hr+b^2=0$
Thus,
$\displaystyle a=5,b=-8h,c=b^2$
supposely i should take the coefficient right?

$\displaystyle 4h^2-8rh+b^2=0$
a = 4, b = -8 , c = 1

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

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

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

$\displaystyle 4h^2-8rh+b^2=0$
a = 4, b = -8 , c = 1

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

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

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.

7. Your new updated post is now correct.

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.
