Question

Determination which of the following polynomials has (x+1) as a factor (II) x^4-x^3+x^2-x+1 Please give me answers it's emergency now please ​

Answer 1

x  4 +x  3 +x  2  +x+1=(−1)  4 +(−1)  3 +(−1)  2+(−1)+1=1−1+1−1+1=1

This is not zero.Then x+1 is not the factor of equation

hope it helps you
