Question

factorize:x³-2x²-x+2​

Answer 1

Answer:( x - 1 )( x - 2 )( x + 1 )

Step-by-step explanation:

x³ - 2x² - x + 2

= x²( x - 2 ) - 1( x - 2 )

= ( x - 2 )( x² - 1 )

= ( x - 2 )( x² - 1² )

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

[ Since , a² - b² = ( a + b )( a - b ) ]

Therefore ,

x³ - 2x² - x + 2 = ( x - 1 )( x - 2 )( x + 1 ) , pls mark me as brainliest

Answer 2

Step-by-step explanation:

| 1 -2 -1 +2

1 | 0 1 -1 -2

|_______________

1 -1 -2. | 0

------

x^2-x-2=(x-2)(x+1)

:- THE FACTORS ARE : (X-1)(X+1)(X-2)
