Get the Quadratic peinormug. A handy formula easily memorized by repetition. It is used in many instances, such as trying to find the roots of an equation, or solving an equation that will not factor with integers.
To solve using the Quadratic Formula:
In any equation
ax^2+bx+c,
The roots can be found by substituting into:
-b(+,-)sqrt(b^2-4ac)/2a
OR
Negative "B" plus or minus the square root of "B" squared minus 4(a)(c), all divided by 2(a).
To solve using the Quadratic Formula:
In any equation
ax^2+bx+c,
The roots can be found by substituting into:
-b(+,-)sqrt(b^2-4ac)/2a
OR
Negative "B" plus or minus the square root of "B" squared minus 4(a)(c), all divided by 2(a).
To solve using the Quadratic Formula:

The roots can be found by substituting into:
-b(+,-)sqrt(b^2-4ac)/2a
OR
Negative "B" plus or minus the square root of "B" squared minus 4(a)(c), all divided by 2(a).
EX:
Hm..
10x^2+13X-5
-13(+,-)sqrt(169+200)/20
>_>
In other words, by substituting the numbers in, you get 13(+,-)sqrt(369)/20.
As you may or may not have guessed, this gives you a very nasty number, which should be approximated and rounded to the nearest thousandth.

Get the quadratic formulamug. A mildly long but sensible and useful equation. Typically used for solving for the two, one, or zero real values of X in a quadratic equation.

Get the Quadratic Formulamug. The act of bunking out of a school lesson to throw a quadrat around a field and pretend you are working. For best results, go to a pub in Wales and try it there!

Get the Extreme quadrattingmug. ex equals the opposite of B plus or minus the square root of B squared minus four AC all over two A (to the tune of the mulbary bush the monkey chases the weasle)
quadratic formula--->
x = -B(+/-)(squaroot of:)(b^2 - 4AC)
----------------------------------
2A
when the equation is
0=Ax^2 + Bx + C
x = -B(+/-)(squaroot of:)(b^2 - 4AC)
----------------------------------
2A
when the equation is
0=Ax^2 + Bx + C

Get the quadratic formulamug. The reason behind dropping out of chemistry. It causes ones brain to recoil in horror and claw at the inner skull wall...it proves that combining math and science is never a worthwhile endeaver...especially when you can just as easily become a biologist and cut up weird things for a living....much more enjoyable.

Get the quadratic formulamug. The act of a female suctioning a plunger to her midriff and sodomizing a male wearing a lampshade on his upon his dome piece whilst a man of the dwarf persuasion repels from the ceiling and sprinkles technicolored pubic hair on your back while listening to russian and/or zimbabwean techno music.
1. Last summer, while visiting my grandparents in Fargo. i walked in to my grandpapa recieving Quadratic Technicolored Lampshade.
2. i first discovered my love for zimbabwean techno when i recieved my first Quadratic Technicolored Lampshade. (QTL)
