Program for TI-86 that allows it to factor

[NutBucket]

Buy a used 89. I only paid about $80 for mine.

Ironically, tonight I traded a friend a 160GB Seagate IDE for his new TI89...well, like-new. Used for the 3 days he took college math before dropping out. >_<

Anyways, he wanted the harddisk as his TI89 was in his dresser for over a year without being turned on. We both got something we wanted without having to touch our pocketbooks, which makes us both winners.

BTW, I did find a program to run on the 86 that factors...I haven't tried it yet, but looks promising.

Thanks for everyone's help!

Not sure about a 86, but on the 89, there is a solve and csolve function that pretty much does the same thing. if you can, upgrade to 89.

the TI has a build in application called "Poly" that lets it factor polynomials. Otherwise, you can program the quadratic formula into it yourself.

Im not sure if it was the ti-86 but back in highschool (last year) there was this kid who would write his own programs in java and put them on his Calculator and it would do EVERYTHING all he would do was put in values, that guy was a genious.

If he was a genius, why did he need a program in a calculator to solve his math problems for him?

it's not exactly that hard. The TI-86 is natively programmed in BASIC, which looks just like JAVA, and any other object oriented language out there.

graphing calculators are the reason all my accounting professors only allow us to use "simple" calcs on tests. :[

Unless they made some major change to TI-BASIC I wasn't aware of, it does not look just like java, and it isn't object oriented.

Hey Shawn! That's exactly what I did do...read the above post where you posted earlier.

There is also an HP calculator that will show work as well as solve the problem. Can't remember what it's called. Been around 4 or 5 years now since I've been in school.

eh? i have no idea what "object oriented" means, but what i mean is, TI-BASIC looks like your typical C'ish programming language, much simpler, but yeah, one look at it and you should be able to identify how it looks. It's not weird like Assembly.

WOW! All along I've had this access, but have never known about it...this works GREAT! Just one thing I have to keep in mind when entering negative numbers is that they come out to what X will equal, so if I have to fill in an equation, like (x-4)(x+1)=0, the X1 comes out as the opposite value. (comes out as positive 4 instead of negative) However, this kicks ass.

Thanks dude! You've saved me a lot of trouble!!!

I was going to post that polynomial solver as well (I'm a day too slow though). The Solver is even more powerful. You don't even need a polynomial when you use Solver. Of course Solver only gives one answer at a time though.

Those two are the most used features for most college classes that need a TI-85/86/92/etc. If you don't know how to use them, learn fast. It'll save you hours on many assignments on many classes.
