Question

factorise it with methord

Answer 1

1x1=1 2x2=2 that's ur answer

Answer 2

The answer is given below :

Now,

${x}^{3} - 2 {x}^{2} - x + 2 \\ \\ = {x}^{2} (x - 2) - 1(x - 2) \\ \\ = (x - 2)( {x}^{2} - 1) \\ \\ = (x - 2)(x + 1)(x - 1)$

which is the required factorization.

Thank you for your question.
