Question 1
x- 2 is a factor.
To find other factors, use synthetic division:-
2 | 4""""-17 """" 9""""18
""|"""""""" 8 """"-18""-18
""|4""""""-9 """"-9"""""0
Gives:-
(x - 2) (4 x ² - 9 x - 9)
(x - 2) (4 x + 3) (x - 3)

Question 2
(x - 1) is a factor (given)
"1|1"""2"""-13"""10
""|"""""1"""""3"""-10
""|1"""3""""-10""""0

(x - 1) (x ² + 3 x - 10)
(x - 1) (x + 5) (x - 2)
