Re: Can TI-85 calcs FOIL?



First off x^2 + 25 does not equal (x+5)(x-5).  :^)
The 85 will not do this with a built-in routine.  I wrote a program for
this but it wasn't too efficient (ie: too long and slow).  There is,
however, a better program written for the 82.  It shouldn't be too
difficult to rewrite the code for use on the 85.  I believe the program is
named PFACT or something along those lines.


Hope this helps.
