TI-89 polynomial factoring help

[dowxp]

I'm trying to do inverse laplace transform and usually on the denominator the terms are not in ax+b form. so say the original form was ax^3+bx^2+cx+d .. and i need it in (ax+jb .. ) and its conjugate, can the 89 do it?

you have to use complex factor or complex expand in the complex menu
