Question

using factor theorem determine whether X + 1 is a factor of x cube + x square minus x minus one or not​

Answer 1

Answer:Yes x-1 is a factor

Step-by-step explanation:

f(x) = x^3 + x^2 - x-1

f(-1)= (-1)^3 + (-1)^2 - (-1) - 1

= - 1 +1 +1 - 1

= 0

Answer 2

Answer:

it is a factor

Step-by-step explanation:

x^3 + x^2- x- 1

so x=-1

(-1)^3+(-1)^2-(-1)-1

-1+1+1-1=0

hence it is a factor
