Question

5. Factorise :
(i) x3 - 2x2 - x + 2​

Answer 1

Answer:

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

By factorisation we get,

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

( x - 2 )       ( x^2 - 1 )

x = 2               x^2 = 1

                       x = 1

Therefore x = 2 or 1 .

Answer 2

Answer:

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

x^3 - 2x^2 - x + 2By factorisation we get,

x^3 - 2x^2 - x + 2By factorisation we get,x^2 (x - 2) - 1(x- 2) (x-2) (x^2-1)

x^3 - 2x^2 - x + 2By factorisation we get,x^2 (x - 2) - 1(x- 2) (x-2) (x^2-1)x = 2

x^3 - 2x^2 - x + 2By factorisation we get,x^2 (x - 2) - 1(x- 2) (x-2) (x^2-1)x = 2x^2 = 1 x = 1

x^3 - 2x^2 - x + 2By factorisation we get,x^2 (x - 2) - 1(x- 2) (x-2) (x^2-1)x = 2x^2 = 1 x = 1Therefore x = 2 or 1. Hope this helps you...
