Question

09) 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)( {x}^{2} - 1)=(x−2)(x

2

−1)

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

Answer 2

Your Question:

$factorise \: \: \: {\green{ {x}^{3} - {2x}^{2} - x + 2}}$

SOLUTION:

${x}^{3} - {2x}^{2} - x + 2$

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

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

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

${\blue{ = = > (x - 2)(x + 1)(x - 1)}}$
