Question

. Determine which of the following polynomials has (x + 1) a factor :
) x2 + x2 + x + 1
(i) x + x + x +*+1​

Answer 1

Step-by-step explanation:

putting x=-1 ,solve

1. (-1)^2+(-1)^2+(-1)+1

=1+1-1+1=3-1=2

hence ,it is not the factor.

2.(-1)+(-1)+(-1)+(-1)+1

=-4+1

=-3

hence ,x+1 is not the factor of any two of the following
