Hellooooo everybody. i have a very distinct feeling that there's something very wrong here...(adsbygoogle = window.adsbygoogle || []).push({});

OK, what i'm trying to do is to get to the quadratic equation through the standard form of a polynomial equation in the second degree.

watch this, and go to this website. it lists the process very briefly http://mathworld.wolfram.com/QuadraticEquation.html...in this picture http://mathworld.wolfram.com/qimg558.gif [Broken] isn't it wrong to put thex+b/2ainsidethe parenthesis with the WHOLE thing raised to the second power?? i mean doesn't that mean that the WHOLE THING INCLUDING the 'x' gets squared?? that's wrong!! aha!! that's wrong!! i knew it!! i knew it!! Nah I'm just kidding there but i really do want to know if that's a typo or not. I think that when completing the square, you should only raise the "b" term in (the standard form) to the second power. like this:

[tex]ax^2+bx+c=0[/tex]

[tex](\frac{b}{2})^2[/tex]

subtract the 'c' and bring it over to the other side, then complete the square:

[tex]ax^2+bx+(\frac{b}{2})^2=-c+(\frac{b}{2})^2[/tex]

is this right, as opposed to the ones shown on that website? :uhh: :uhh:
