Question

factorise: x3-2x2-x+2​

Answer 1

Answer:

Step-by-step explanation:

To factorize polynomial we have to figure out at least one zero.  

1 is zero of the expression.  

(x³ - 2x² - x + 2) ÷ (x - 1) = x² - x - 2

(x - 1)(x - 2)(x + 1)

Answer 2

$\huge\boxed{Answer}$

x³ - 2x² - x + 2

x²(x - 2) - 1(x - 2)

(x² - 1) (x - 2)

(x + 1)(x - 1)(x - 2)
