Question 95988
{{{(x^3 + 2x^2 - 5x - 6)}}}
x(3) + 2X(2) - 5x - 6, x + 3
.
Use synthetic division to solve:
[x=-3]
.

Coeeficients: 1 +2 -5 - 6
.

1+2-5-6
0-3+3+6
______________
1-1-2+0
.
So,
{{{(x^2-x-2)}}} is the other factor.
.
Check by multiplying the two factors to get the orginal product:
{{{(x^2-x-2)}}}(x-3)
