Question

factorise
x^3-2x^2-x+2​

Answer 1

2, 1 and - 1

Step-by-step explanation:

first of all write it in a place lol

x^3 - 2x^2 - x + 2

group them into two parts based on commons

(x^3 - x) - (2x^2 + 2) since , well its observable.

next take out the commons

x(x^2 - 1) - 2(x^2 - 1)

now ( x - 2 )(x^2 - 1)

taking tge values of x we get

2 , positive or negative 1
