Do you know the Quadratic Formula?

[Arcadio]

I just want to know what percent of computer professionals or enthusiasts know the Quadratic Formula without looking it up in a book....

 

[benzylic]

first you take the opposite B plus or minus the square root of B^2 minus 4AC all over 2A

 

[Crono]

[-b+/- sqrt(b^2-4ac)]/2a

Yes, stored in brain. I can't remember trig relationships and formulas, though. I always hated trig and geometry, for some reason.

 

[Zim Hosein]

Is the Quadratic Formula stored in your brain?

No. I need to look it up when (if) I need it. 😱

 

[looker001]

No, have't used one in about 10 years.

Bonus points: Do you remember the derivation?

 

[evident]

yeah, but i forget what it's for (like when to use it )

 

[Fenixgoon]

[-b +- sqrt(b^2 - 4ac)]/2a

bizatches! 😛

 

[Gunslinger08]

I use exactly 0% of what I learned in school.

 

[sash1]

i haven't used it in forever, but yes i still know it

 

[jlee]

This.

 

[SSSnail]

I use it every time I pay for my Big Mac at a drive through.

Complete the square?

 

[Arcadio]

JohnCU knows it, btw.

 

[natto fire]

Nope, but I do remember the Pythagorean theorem.

let me guess... you are an artist....

Why? You'll learn far more if you look it up than if you limit yourself to what you remember from high school.

I'm sorry, but that makes no sense at all.

 

[BlackTigers]

Soh Cah Toa

y=mx+b
y-y1 = m(x-x1)

d= y2-y1/x2-x1

That's all I care to remember really. Or at least, the main ones that are burned into my brain.

[SampSon]

Don't remember it. Don't need to remember it.

 

[JDawg1536]

I had it memorized in high school. It helps you remember it if you kinda sing it.

I'm sorry you didn't get it.
