Answer:
The answer to your question is: (x - 2)(x + 9)(x + 1)
Step-by-step explanation:
x³ + 8x² - 11x - 18
find the prime factors of 18
18 2
9 3 Try : ± 1, ±2, ±3, ± 6,± 9
3 3

Synthetic division
1 8 -11 -18 2
2 20 18
1 10 9 0 First factor ( x - 2)
x² + 10x + 9 = 0
(x + 9)(x + 1) = 0 polynomial of the form x² + bx + c
x³ + 8x² - 11x - 18 = (x - 2)(x + 9)(x + 1)
