Question

1. Determine which of the following polynomials has (x + 1) a factor:
EXERCISE 2.4
(ü) x4 + x3 + x2 + x+1
​

Answer 1

Step-by-step explanation:

(x + 1)=0

x=-1

PUT THIS VALUE IN x⁴ + x³ + x²+ x+1

( -1)⁴+(-1)³+(-1)²+(-1)+1

=1-1+1-1+1

=1

which is not equals to 0

so x+1 is not a factor
