I want to transfer my programs from a TI - 84 to a casio fx- 9750GII, how do I do this?

No, you'll have to manually type it in. The TI and Casio programming languages are similar but not identical, and the internal representations are completely different. Even if you transferred a program from one to the other, it would only be a meaningless collection of bytes.

Programming in TI-84 Plus? I'm a High School student?

There is nothing wrong with your English. The problem with your request is that the program you are talking about is NO program at all, but a collection of formulas that may serve as a cheat sheet. If your teacher wanted you to make this program he would have shown you the steps to key in. Besides it would be a lot more efficient to just write these formulas on the board. Sorry, there will be no help from me.
Your formulas 2 and 3 are useless, and formulas 7 and for the real solutions of a quadratic equation are wrong. The right member should be multiplied by 1/a.
How about trying to learn your formulas by heart? It is good for your memory and you will avoid being caught cheating.

How to solve polynomials

That depends on the order of the polynomial. If the polynomial is of second order, the quadratic formula will give you its roots. There are similar formulae for third, fourth, and fifth order polynomials, and it has been proven that no such formulae exist for higher-order polynomials.
Some TI calculators have a numerical solver which can produce numerical solutions to arbitrary polynomials. Since you declined to specify the model of your calculator, I'm afraid I can't tell you whether yours has one or not.
If you need further assistance, please reply to this post and be sure to specify the model of your calculator.

Change TI 84 OS to TI 89 OS??

And why, pray tell, would you do such a thing? You will ruin your Ti84 Plus Silver Edition and will not have a working TI89. Besides, TI connect will refuse to transfer it.
If you like the capabilities of the TI89 Titanium, buy a cheap or used one on e-bay or and spare your TI84PLus SE.

Why do some TI83 program work on a TI84 plus and other don't?

Ti 83 and ti84 really have no difference and operate the same. There was something different or you had varibles used by multiple programs that conflicted w/ the ti84 and it would have done the same on the ti83. If you like to rework it and need help email me at

kinda. The TI-85 programs differently, lacks a table feature, is not upgradable, has redefinable keys, has a larger screen, is smaller, energy efficient, TI-86 semi-compatible, and is older.
The TI-84+ has archive memory, flash-upgradable, FSTN (clearer) screen, 16*8 screen, USB On-The-Go compliant, almost a centimeter longer, assembly language support, and a tad bit faster.

TI-82: $89
TI-83 Plus: $79-99
Free TI-85: $0
TI-84 plus: $119.99
TI-84+SE: $129-139
TI-89 Titanium: $149
