Answer:
The completely factorized form is: (x - 1)(x + 2 )(x - 3)
Step-by-step explanation:
To find the solution, we use Ruffini's rule:
1 - 2 -5 + 6
We first divide by (x-1): 1 1 -1 -6
________________________
1 -1 -6 0
Then divide by (x + 2): - 2 -2 +6
_______________________
1 -3 0
Then, the rest of the division is: x - 3
Thus, the completely factorized form is: (x - 1) (x + 2 ) ( x - 3)
