You can put this solution on YOUR website! Use the factor theorem to decide whether the second polynomial is a factor of the first.
f(x) = x^3 + 4x^2 + x - 6; x - 1
-----------------------------------
x-1 will be a factor of f(x) is f(1)=0
Using synthetic division you get:
------------------------
1)....1....4....1....-6
.......1....5....6..|..0
Remainder = 0, so f(1)=0, and x-1 is a factor of f(x)
================
