i just go t a new TI-89 within the last week and am in the process of essentially re-writing my old programs from the TI-84

i was trying to take advantage of the "factor ()"
the code that is having the problem is:



Code:
ElseIf bol=3 Then
 Disp a,b,c

 disp factor( a*x^2 + b*x+c)


the disp a,b,c lines works and displays the numbers stored as a b and c
that is probably not the right way to show the factorization of that
i continue to get an "undefined variable" error

what i am trying to do is get the factorization to show on either the home screen or the I/O screen. any help would be appreciated

thank you

It works for me. Are you sure you don't have the variable x defined as something weird?
