X^3-2x^2-x+2 factoriseanswering the correct will be marked as brainliest and wrong will be reported and those who answer it correctly i will start following​​

Answer»

Answer:

GIVEN that x³ – 2x²– x + 2

Grouping the 1ST and 3nd terms together and the 2nd and 4th TERM together:

x(x² – 1) – 2(x² – 1)

x³ – 2x²– x + 2 = (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) (x- 2)
