TI-93 Plus calculator
i have a TI-83 plus calculator & my teacher said you can download the quadratic formula into it. okay. well i went to "PRGM" and made a new program called "QUADFORM". so now my calculator says:
PROGRAM:QUADFORM:
and it's blank.
uh, what do i put in? like i googled it but it gave all this complicated stuff. can someone give me a detailed, easy to understand step-by-step list of instructions on how to input the quadratic formula into my TI-93 Plus calculator?
i promise i'll love you forever :] (and rate you a five!)

well any answer you get isn't gonna be much simpler than what you find online, since programing it is relatively complicated.
ill try to make this simple.
open up the program in edit mode
push prgm, push right, and push enter on Prompt
type in A,B,C
push the square root key
type in B^2-4AC) then push the sto button thats above main then put D
push the square root key
type in B^2+4AC) then push the sto button thats above main then put E
type in (-B+D)/(2A) push the sto button, X
type in (-B-D)/(2A) push the sto button, Y
push prgm, right, and push enter on DISP, then put an X
push prgm, right, and push enter on DISP, then put an Y
push 2nd, quit
now when you run the program, it should ask you to enter A then B then C
its in the form Ax^2 + Bx +C
it should then spit out the answerss for you.
or do it a much simpler way, ask someone in class who has it to transfer it to you via the link cable.
