Question

Factorise the Following
(i) x³-2x²-x+2

Answer 1

-: Factorisation :-

➡x³ - 2x² - x + 2

➡x² (x - 2) - 1 (x - 2)

➡(x - 2) (x² - 1)

➡(x - 2) (x + 1) (x - 1)

Answer 2

Answer:

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

Step-by-step explanation:

when x = 1

p(1) = 1-2-1+2

p(1) = 0

so, (x-1) is a factor of p(x)

when x = 2

p(2) = 8-8-2+2

p(2) = 0

so, (x-2) is a factor of p(x)

when x = -1

p(-1)= -1-2+1+2

p(-1)=0

so, (x+1) is a factor of p(x)

so, factorisation of p(x) -

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