Quadratic Equations on the TI-83+, TI-84+
Posted by: raysmithtx Post date: December 24th, 2010
How to use the TI-83+ or TI84+ to compute the solutions to a quadratic equation using the quadratic formula programmed in. Also how to work with the graph of the equation, and non-real solutions.

@aborne thanks

charlesinator5, yes, this is possible only on the TI-89 or the TI-nspire CAS.

Respond to this video…
go to my math page which you see as a link at the end of the video and it will be there.

THANKS! this video really helped me, only in the beginning you said that you would show the instructions for how you made the program at the end of the video….and the instructions for making the program wasn’t there at the end…T.T

great video! Is there a way to factor these second degree polynomials on the ti 84. (Not just what x equals but the actual factors) Thanks if you can help!

how can i re install this program

@aborne congrats for the kids. And thanks for the video.

i love algebra.

Wow, I remember those days of my two year old keeping me up. I used to literally have to crawl out of his room on my hands and knees after getting him back to bed.
Don’t take any offense to my post. I am stressed with this Algebra and when I could not hear your video, it only made it worse.

@donovanfonseca Yes I made the program but I’m not the first, and I did not “create” the quadratic formula. This is a fairly common program and it’s not hard to make many of these helpful programs. You should make these yourself, it will help you learn the math too! Good luck.

@djrea4815 Currently I use a mac program called iShowU HD and Texas Instruments SmartView, and yes that is an emulator.

@seandelevany Dude, you would be quiet too if you were making this video while your kids were sleeping. If you wake up a 2 year old, you’re screwed.

It’s okay- there is nothing wrong. The INPUT prompt on the TI-83+ does not prompt the user with the variable name; you get only the “?” to ask the user for input. Just go with it.

I am also havint the sma problem as coffeegirl. I have a TI-83 Plus I downloaded your program and installed it. And for some reason when I hit enter to run the program I see a diffrent screen then your sample. This is what shows up on mine .
PROGRAM QUAD
ENTER A, B, C:
?
SO IM NOT SURE WHATS WRONG…. hope u can help resolve this!

how did u make this into a video?. like whatt program did u use?is that a TI-84 Emulator?

Dude, you have a great vide3o but you have to speak up.

When i hit enter after putting in all the coefficents it only shows me 1 answer. How do i fix this?
December 24th, 2010 at 10:35 pm
Don’t worry; you’ll get it. Press the PRGM key, and execute the program. Don’t be afraid to play around & explore your new calculator!
December 24th, 2010 at 10:43 pm
Hi just curious but could you tell me the exact buttons that you pressed after inputting the Program part? My calculator is a TI-84 Plus Silver ed if it makes any difference.
My calculator won’t graph the program…it’s new and just out of the box.

How did you get quad??
Did you make the program?
December 24th, 2010 at 10:46 pm
I don’t know. You probably didn’t enter the program correctly. Try loading it directly with the QUAD.8xp file from my website.
December 24th, 2010 at 10:50 pm
in my calculator after I enter the values for A, B, C, and hit enter I do not see the discriminant . Why?
