1. ## RELEASE: quadtratic eq. solver for TI

yeah so i was getting pissed at my physics hw cz i had to solve for the quadratic equation a ****load of time and its a lengthy process

well i coded a auto solver (root finder)
notes: prompt is found in PRGM, push right to go to I/O and then option 2
typethis in:
Prompt A
Prompt B
Prompt C
(-B+*square root sign*BB-4AC))/(2A)
Disp Ans (this is found near Prompt and Ans is 2nd (-) (next to 0))
(-B-*square root sign*BB-4AC))/(2A)

this is of course BEFORE i found out my TI-84+ had a built in equation solver and also a variable solver >< (variable solver was good today in class because we did **** like 3x-4.5y+9z=22)
-= Double Post =-
it will give the positive root and then the negative

2. Cool, I'm sure this will be useful to many :)

3. it will for me :)...

4. Hehe, im bored.

Heres better code

Prompt A,B,C
Disp (-B+*square root sign*BB-4AC))/(2A), (-B-*square root sign*BB-4AC))/(2A)

2 lines FTW

5. psh im l337
