Question

determine which of the following polynomial has X + 1 as a factor x cube -x square - x + 1

Answer 1

Hello !!


X + 1 = 0


X = -1





P( X ) = X³ - X² - X + 1



P ( - 1 ) = (-1)³ - (-1)² - (-1) + 1


=> -1 - 1 + 1 + 1


=> 2 - 2

=> 0


Remainder = 0


So,


( X - 1 ) is a factor of the given polynomial.
