Question

factorise x³-2x²-x+2​

Answer 1

Answer

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

step by step process

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

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

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

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

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

Answer 2

Answer:

Question :-

➪ x³ - 2x² - x + 2

Formula used :-

➪ a² - b²

➭ (a + b) (a - b)

Solution :-

➪ x³ - 2x² - x + 2

➭ x²(x - 2) - 1(x - 2)

➭ (x - 2) (x² - 1)

➭ (x - 2) {(x)² - (1)²}

➭ (x - 2) ( x + 1) (x - 1)

∴ The value of x³ - 2x² - x + 2 is

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