Answer:

Apply remainder theorem

x+1=0

x=−1

Put the value of x=−1 in all equations.

(i) x3+x2+x+1=(−1)3+(−1)2+(−1)+1=−1+1−1+1=0

Then x+1 is the factor of equation

(ii) x4+x3+x2+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

(iii) x4+3x3+3x2+x+1=(−1)4+3(−1)3+3(−1)2+(−1)+1=1

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

(iv)x3−x2−(2+2)x+
