Who can list the quadratic equation off the top of their head correctly without looking it up???
Don't post it, just say if you can or can't...
I had to look it up, I had the sqrt term backwards... rusty old memory of mine(too many dead brain cells) 10/2/2007 11:56:31 PM |

Negative B,
Negative B,
Plus or minus square root! Plus or minus square root!
B squared minus 4 A C, B squared minus 4 A C,
Over 2 A. Over 2 A.

The last two lines might be 'All over 2 A.' but its about the same. Its sung to the tune of some lullaby/song you learn in kindergarten. 10/3/2007 9:36:36 AM |

Well you fucked up.
You meant: quadratic formula OR EQUIVALENTLY, the solution to a quadratic equation.
Quadratic Equation (general form): ax^2 + bx + c = 0.

A few times a week for me. I can usually do it in my head if the coefficents are whole numbers and/or the equation is 3rd order or less.10/3/2007 2:30:58 PM |

^ same here... in fact, i can get an answer within +- 10% no matter what the coefficients are (in my head).
and for those who tried to derive it, you have to know how to complete the square, which almost no one understands/knows/remembers (among non-math majors). 10/3/2007 3:44:55 PM |
