Answer:

Option (3)

Step-by-step explanation:

Given polynomial is (x³ - 2x² - 13x - 10).

If (x - 5) is a factor of the given polynomial, other factors can be found by the synthetic division.

5) 1      -2     -13      -10

  -       5       15      10

   1       3       2         0

Therefore, other factor of the given polynomial will be (x² + 3x + 2)

And the factored form of the polynomial will be,

(x - 5)(x² + 3x + 2)

Option (3) will be the answer.
