Answer:
(x +1), (x -5) and (x +1)
Explanation:
The computation of the factorization is shown below
Data provided in the question
[tex]X^3 - 3x^2 - 9x - 5[/tex]
Based on the above information, the factors are
Now we have to open these equations in order to get the factors which are as follows
[tex]= x^3 + x^2 - 4x^2 - 4x - 5x - 5[/tex]
[tex]= x^2( x + 1) - 4x ( x + 1) - 5(x + 1)[/tex]
[tex]= (x + 1) (x^2 - 4x - 5)[/tex]
[tex]= (x + 1)(x^2 -5x + x - 5)[/tex]
So,
= (x + 1) (x - 5) (x + 1)
Therefore the (x +1), (x -5) and (x +1) are the factors of the mention polynomial give in the question
