Question

factorise x³-x² - x +1​

Answer 1

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

Step-by-step explanation:

x³-x²-x+1

x²(x-1)-1(x-1)

(x-1)(x²-1)

(x-1) ((x)²-(1)²)

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

Answer 2

Answer:

given to factorize x³ - x² - x + 1

=> x²(x- 1) - 1(x -1) [ take out commom factors ]

=> (x -1) (x² - 1) [ x² - y² = (x + 1)(x - 1) ]

=> (x -1)(x + 1)(x 1)

=> (x -1)(x -1) (x + 1) answer
