My calculator, TI-84 plus won’t run application. “Window Size Error” Help???
October 9th, 2007 at 7:58 pm
go to window
make sure that the xmin, and xmax dont conflict ex
xmin=0
xmax=-10
same with y min

My program is way better
:clrhome:promptA,B,C
B^2)-4(A)(C)->W [-> is the STO button]
:If W/=0
:Then
:-B+suareroot(W->X
:X/(2A)->Y
:Output(4,1,”ROOTS ARE:”:Output(5,1,Y)
:-B-squareroot(W->I
:I/(2A)->J
:Output(6,1,J)

it wont run it says “err: archived”

how do u program the quadratic equation solver on the TI-84 Plus?

This is the easiest program to set up and understand
-> is the STO button
* is times
ROOT is the square root button
SQUARED is X2 or the square button

I was trying something similar to this program, and I couldn’t execute the program correctly. It didn’t state the answer, only the name of the program I was trying to run. That was it. Any help would be greatly appreciated.

I just had the same problem sayoing “err: archived” i solved it by going to 2nd ‘mem’ then go to 2: Mem mgmt/del… then go to 1:All and make sure there are no ‘*’ beside your program “QUADRATIC” or any of the variables it is using
To unasterik simple press enter beside the item.
Hope this helps altho it was a year late

Here is a program I wrote for the quadratic equation. It’s simplistic and gives the answer even if it is a nonreal answer.
Prompt A,B,C
a+bi
Disp (–B+√(b^2-4AC))/(2A)
Disp (–B-√(B^2-4AC))/(2A)
Hope this helps anyone looking for a simple program to do this.

I am looking for a algebra progam to download to my Texas Inst. ti 84. I need a program that will solve, factor,

These are the two programs that you need:
Prompt A,B,C
a+bi
Disp (–B+√(b^2-4AC))/(2A)
Disp (–B-√(B^2-4AC))/(2A)
This program will also display nonreal answers
Prompt A,B,C
(-B+ROOT(BSQUARED-(4*A*C)))/(2*A)->Q
(-B-ROOT(BSQUARED-(4*A*C)))/(2*A)->Z
isp Q
isp Z
-> is the STO button
* is times
ROOT is the square root button
SQUARED is X2 or the square button
This is the easiest to understand

Tom thats almost right exept when the A value is more than one, then you have to multiply the answer with a decimal with the a value, but all in all thank you.
if you have no idea what im talking about plug in 2xsquared+15x+7
