TI-84 Plus CE: How to Solve Equations

[@NouraldinRRHammouda]

Even after 6 years this is a life saver

[@fuse_kingpin5084]

Thank you , I had a algebra test coming up and you saved me last second !!!

[@Ghost_Tree]

Me too

[@bookinit5216]

Thank you so much for this explanation! Your video answered all of my questions, I really appreciate it!

[@IndirePolaris]

How can I do this on a ti-84 plus? My solver doesn't have the E1 and E2 box.

[@Ky-vv8nj]

It's because you're not using mathprint. Press [ mode ], at the top, change it from CLASSIC to MATHPRINT. It will work after that.

[@sb2h]

Yes you can. If there's just one place for you to enter the equation with x= directly below it, you need to set your equation = to zero (ie: 2x=4 becomes 2x-4=0) and it will solve for x

thanks mate. needed this for ap calc bc

[@joshvalle5521]

Thanks man, Im floating between a C and B in calc right now, and my tests are only a few questions, so this is literally a difference between a pass or a fail

[@andrepoghosyan8269]

how did it go?

[@evelynzhao9065]

That was very helpful. Thank you so much!

[@lukaesquen4057]

You saved me bro The teacher I had taught me nothing so I had to resort to you

[@rockopaws1610]

Is there not a way to get both values of x? Older calculators can do that

[@Mghrf]

U can build a quadratic function in the program Just search for how to program a quadratic solver in ti-83/84

[@colinb8952]

is there a way to use this to find complex roots?

[@markvicente6071]

Very helpful, thanks :)

[@donovanhill240]

Man’s a lifesaver

[@GoldenGaming-th9oc]

It says Error:bad guess what do I do? How do I make a guess

[@leeprimeroessler3277]

Just bought my first ti-84. I have to say this solver is crappy compared to the hp’s and casio’s. It acctually can’t display both solutions from an second degree?

[@navyanair3222]

thank you so much

[@leratonlaveurbg882]

Thank you !

[@OakRidgeKennels]

Just a tip folks, you can use the X symbol for another other letter other then the X on the TI-84 Plus CE.

[@liamperry1306]

How I have a ti 84 plus ce and can't figure out how

[@OakRidgeKennels]

@@liamperry1306 Hello, Perry! Should be labeled on the calculator.

[@stephanierodriguez3362]

Mine just puts “T” I’m not sure how to go back to the “x”

[@OakRidgeKennels]

​@@stephanierodriguez3362Perry, it's been a long time. I can't remember it's been a long time

[@stephanierodriguez3362]

@@OakRidgeKennels I’m not perry lol

[@Avighna]

2:30 ah yes, the wonders of newton-raphson. Or atleast, I’m guessing that’s how it solves equations.

[@23StudiosSports]

Why would they make the graph button the solve button fml

[@jessiemayfield6749]

I’m sorry what? You’ll press graph again and it’ll tell you x=1/3 then quit. I got e1-e2=0 no x value!

[@naidely4768]

ohhhhhh

[@patrickosullivan6736]

sus

[@guloguloguy]

your explanation is fair, but, your fingers click around way too fast, and it's impossible to see what keys you are choosing...show the entire keyboard, and, keep your hand out of the way!!! [use only one finger, or, a pencil!]

[@Kraiden85]

I get the wrong answer here with my TI-84 Plus CE-T -2(5c - 10) + 16 = 4(2 + c) Answer should be c=2 but it the calculator gives the wrong answer. I checked my inputs 4 times and I filled in everything correctly. When I use c it says c=0 when I use x instead of c it says x=-0.3030303

[@Mghrf]

I try it and i got X=2

[@cheekymonkeygirl3378]

Omg, who has a team for that? I love algebra. I do it myself anyway. Not worth the hassle. 😢
