Question

Examine whether (x+1) is factor of x^3+x^2+x+1

Answer 1

0 is the answer

Step-by-step explanation:

x+1=0

x = -1

-1³+(-1)²+(-1)+1

-1+1-1+1

0

Answer 2

Step-by-step explanation:

f(x)=x³+x²+x+1

f(-1)=(-1)³+(-1)²+(-1)+1

=-1+1-1+1

=0

Hence (x+1) is a factor of the above given polynomial
