I don't see how the TI-89 can make proper simplification to the
following ex:
(1*(x-(-1+sqr(3)*i)))/((x-(-1+sqr(3)*i))*(x-(-1-sqr(3)*i)))
The problem is that the TI take it as:
(1*(x-(-1+sqr(3)*i)))/(x^2+2*x+4)
and now we only get zero in the denominator when inserting a factor of
it.
Is there a way to solve this problem ?
