Factor by grouping, if possible. Show all necessary work.
x^3 + 3X^2 - 2x - 6
-----------------
Comment: Usually, when you have 4 terms to factor, you should
think of arranging the 4 terms.
------------------
Your Problem:
x^3-2x + 3x^2-6
---
Factor the 1st two and the last two terms separately:
x(x^2-2) + 3(x^2-2)
----
Factor againL
(x^2-2)(x+3)
