For nonreal answers, just use:

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

But go into mode, go down 6 times, then go right once, and just push enter. It will be set up to display nonreal answers now.

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 (â€“B+âˆš(b^2-4AC))/(2A)
Disp (â€“B-âˆš(B^2-4AC))/(2A)

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

These are the two programs that you need:

Prompt A,B,C
a+bi
Disp (â€“B+âˆš(b^2-4AC))/(2A)
Disp (â€“B-âˆš(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

Hope this helps anyone looking for a simple program to do this.

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

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.

This is the easiest program to set up and understand

rompt 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
