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)

but seriously, how often do you use the quadratic equation?


I think I might've used it twice since 8th grade.

if you do engineering you run across it relatively often, actually.

No one ever taught me the song

Thus, I sort-of know it... I usually screw up the stuff under the radical.

I never learned the song either. I think the other class at my school did, though, and we were all wondering wtf they needed a song.

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.

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.

it's hard to forget when you learn those stupid songs. that's why they make them so catchy. to hell with the system for their silly songs.

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.

^ 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).
