Answer 2

x³ − 2x² − x + 2 = (x - 1) (x + 1)(x - 2)

Step-by-step explanation:

Correct Question should be

गुणनखण्ड ज्ञात कीजिए

x³ − 2x² − x + 2

f(x) = x³ − 2x² − x + 2

f(1) = 1 - 2 - 1 + 2  =0

=> (x - 1) गुणनखण्ड

                   x² - x - 2

(x - 1)       _|  x³ − 2x² − x + 2  |_

                    x³ - x²

                 ______________

                         -x² - x + 2

                         -x² + x  

                        ________

                                 -2x + 2

                                  -2x + 2

                                   ______

                                         0

x³ − 2x² − x + 2 = (x - 1)( x² - x - 2)

=> x³ − 2x² − x + 2 = (x - 1)( x² - 2x + x - 2)

=> x³ − 2x² − x + 2 = (x - 1)( x(x - 2) + 1(x - 2))

=> x³ − 2x² − x + 2 = (x - 1)( (x + 1)(x - 2))

=> x³ − 2x² − x + 2 = (x - 1) (x + 1)(x - 2)
