factor the polynomial x^3+3x^2-10x-24 completely knowing that x-3 is a factor.
--------
Use synthetic division:
---
3)....1....3....-10....-24
.......1....6.....8.....|..0
==============
Quotient: x^2 + 6x + 8
Factor:(x+4)(x+2)
============================
Factor Form: (x-3)(x+4)(x+2)
=================================
