Question

Determine whether x+1 is a factor of x^3+x^2+x+1​

Answer 1

Answer:

x + 1 = 0

x = -1

putting x = -1 in the equation

x^3+x^2+x+1​

1^3+1^2+1+1​

4

since the answer isn't 0 so it is not a factor

Step-by-step explanation:

Answer 2

Answer:

To determine whether x+1 is a factor, we take x = -1

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

= (-1) + 1 + (-1) + 1

= - 1 + 1 - 1 + 1

= 0

since our answer is 0, therefore x+1 is a factor p(x).
