Answer 2

Answer:

x³ – 2x² – x + 2

Step-by-step explanation:

  x³ – 2x² – x + 2

= x(x² – 1) – 2(x² – 1)

= (x² – 1) (x – 2)

Using the identity:

                              a²  − b²  = (a + b) (a- b)

  (x² – 1) = (x + 1)(x – 1)

= (x – 1) (x + 1) (x- 2)

Answer is (x – 1)

                 (x + 1)

                 and (x- 2)
