Question

factorise: x³-2x²-x-2​

Answer 1

Answer:

Step-by-step explanation:

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

=X^2*x-2-x-2

=x^2*-4

Answer 2

Step-by-step explanation:

$\bold{Correct \: Question - } \\ {x}^{3} - 2 {x}^{2} - x + 2 \\ \\ \bold{Answer -} \\ \\ {x}^{3} - 2 {x}^{2} - x + 2 \\ {x}^{3} - {x}^{2} - {x}^{2} + x - 2x + 2 \\ {x}^{2} (x - 1) - x(x - 1) - 2(x - 1) \\ (x - 1)( {x}^{2} - x - 2) \\ (x - 1)( {x}^{2} + x - 2x - 2) \\ (x - 1)[x(x + 1) - 2(x + 1)] \\ \bold{(x - 1)(x - 2)(x + 1)}$
