You can put this solution on YOUR website! factor x^3+2x^2-5x-6 by using synthetic division.
--------------------------
f(-1) = 0, so -1 is a zero.
-----------------------------
-1)....1....2....-5....-6
........1....1....-6....|..0
Remainder = 0
Quotient = x^2+x-6
which can be factored as (x+3)(x-2)
-----------------------
Factored form = (x+1)(x-2)(x+3)
=================
