Is it possible to compute complex Residues at the TI-89 ?



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 ?
