Programming The Quadratic Equation into a TI-89 Titanium Calculator

There is no audio yet. I still have to record it, but it will describe everything that I am doing in the video

[@swaglord1404]

Found out that if you hit f2 on home you get an option called "solve." Press enter on solve so you get solve( written on your home screen. Now put in your equation example. solve(3x^2-13x+10 after this you should press =0,x) to solve for zero in terms of x and close the equation. The final sould look like
solve(3x^2-13x+10=0,x)
then it should tell you the two terms x should equal

it says "too few arguments"

[@inx1819]

@@mariobros237 you need to specify which variable (or variables) you're solving for
solve(,x) will solve for x

omg thanks alot. need this for psat in 10 days.

[@Lucy-ew9yh]

you sir, are a wonderful person. I cannot thank you enough for this!

[@DavidDavid-fp6gv]

No he’s an idiot the ti 89 already has this feature built in

[@davomo89]

I know this was posted 2 yrs ago, but THANK YOU!!! really helps me save time in physics!!!

[@inx1819]

@ateb3 Exactly. People buy these calculators and don't even know how to use them lol

[@yaribiberriosacevedo1526]

thanks dude!!! amazing from Puerto Rico here. if you can do more programs videos for this calculator. THanks a lot!!!!!!

Why the output 100 and output 64,80 ????

[@mrlittlez7157]

Why the 100,0, and the 64.80,on the outputs. Where do these numbers come from?

[@matevzstegnar5171]

Thx a lot man.

[@breadams6952]

This is perfect! Thank you!!

[@Broadway1982]

Thank you Sir!!!! Keep making more videos.

[@alexfraley6598]

thanks so much! super helpful

[@cd78]

This is fucking superb...

[@saadalabdali9982]

Awesome video

[@sethnewsome7368]

OMG! If you take the time to write the program then it is the best thing since sliced bread!

[@boratsagdiyev3936]

Great stuff, thank you.

You the MVP

FFFFing Amazing...Thank You

thank you!!

Thank you so much!!! :D

[@explorefoodculture]

thanks man

[@rjravaz8283]

what did you type in from 27sec to 37sec of video? Awesome video

[@RemWHale]

Why did you put in those ranges (100,0 & 64,80) and did you HAVE to put in the equation in another line? Why?

[@RemWHale]

Ah! Those are the coordinates from the last line. I counted.

[@RemWHale]

Problem - it needs "If imaginary, use i."

[@JoshTheGingerProductions]

any idea how to do that?

[@guduin1]

thanks

[@mrcoffee315]

keep posting tutorials to learn more stuff

[@Henysipper]

If my answer is a large answer how do I view Solution 1? I can see solution 2 no problem. The values are a=-16, b=20, c=80. Thank you.

[@SequinBrain]

Probably too late for any purpose, but jic, I don't have this exact program, but there are lines of text on my screen, I got -160 + 32*sq.rt.(295)*i and -5/8 - sq.rt.(295)/8*i, all of which fit on the screen. Do you have the numbers after "Output" punched in correctly?

[@Henysipper]

cool. I think I found a way around it back then. But thanks for replying. @@SequinBrain
