Possibly across the street from a school. Maybe the kid sat at a window in math class, and needed some sort of way to remember the quadratic formula for a test.
THAT'S HOW MY TEACHER TAUGHT IT TO ME!!
Also, SOHCAHTOA.
Sine  Opposite over Hypotenuse; Cosine  Adjacent over Hypotenuse; Tangent  Opposite over Adjacent.
It's things like this that saved my ass in Geometry and Algebra 2.
Now I'm in Stats and it's like "forget everything you learned, you don't need it anymore" and I'm like "hell yes."
Gif unrelated.
i dont know why. ive never been helped by those kinds of things. i just memorize things well i guess. except radians always **** me. i dont have any idea why
+4
#2 to #1

That just means that you have to calculate both the plus and the minus answer to the equation.
so you would calculate both:
b  (b^24ac squared) over 2a
and:
b + (b^24ac squared) over 2a

>Side windows on has the quadratic equation and the other has molecular formula for glucose. They must of known I liked science, but it was so childishly done.
>Still don't know who did it no name was left on it
>But seriously asking someone to "promz" with the quadratic formula wtf
how my awesome 10th grade math teacher taught the quadratic formula and I never ******* forgot it:
Once upon a time, there was a bee. It was a sad bee, one might even call it a negative bee. However, it heard about a party later that evening. It considered the pluses and minuses of attending the party. Finally, it decided to join the party and went inside the house (square root). Inside, there was bee square dancing, and poker, where a bee lost even though he had four ACes.
The whole party was over at 2Am.
I wrote a program in my calculator everytime I need a formula in school so once I learn it I never have to actually know it again. ^.^ just plug in A= ? B=? and C=? for the quadratic equation. haha
