Question

5. Factorise
x3-2x2-x+2​

Answer 1

Answer:

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

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

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

=(x-2){(x)^2-1^2}

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

Answer 2

Answer:

$x^3-2x^2-x+2\\= \left(x^3-2x^2\right)+\left(-x+2\right)\\= -\left(x-2\right)+x^2\left(x-2\right)\\= \left(x-2\right)\left(x^2-1\right)\\= \left(x-2\right)\left(x+1\right)\left(x-1\right)$
