Question

09) Factorise x²- 2x² -x+2​

Answer 1

Your Question:

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

SOLUTION:

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

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

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

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

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