Question

x+1 is a factor of the polynomial p(x) = x^3+x^2-x-1​

Answer 1

Answer:

x + 1 is a factor of this polynomial.

Answer 2

Answer:

yes it is a factor

Step-by-step explanation:

X+1=0

X=-1

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

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

= -1+1+1-1

=0

p(-1)=0

so X+1 is a factor of p(x) = x^3+x^2-x-1
