TI-82 & TI-83 Quadratic Equations
This program will solve quadratics with real or imaginary roots. Answers are given in factored radical form when appropriate and imaginary roots are followed by "i." Because of the formatting limitations for fractions with the TI-82/83, the -b/2a and the fraction, if any, before the radical are listed separately. While I don't like this, but I know of no way to prevent it at this time. The only input required for this program are a, b, and c when prompted.
DISCLAIMER: This program is free, and, therefore, I make no claims about it's efficacy, efficiency, or proper operation. If you find a problem with this program, or can suggest an improvement, please e-mail me at firstname.lastname@example.org .
Use of this Program: You may use this program freely for your own personal use and for the use of other students, but use for publication or any means of profit requires my permission.
Memory Usage: This version of the program uses 312 bytes of memory. I estimate it will take an inexperienced programmer about 20 minutes to enter by hand.

The answer to quadratics such as 2x -6x +10 may look a little strange because of the formatting limitations of the TI Calculators. It will appear like this:
If R =
