Apply remainder theorem

=>x + 1 =0

=> x = - 1

Replace x by – 1 we get

=>x4 + 3x3 + 3x3 + x + 1

=> (-1)4+ 3(-1)3 + 3(-1)2 + (-1) + 1

=> 1 -3 + 3 - 1 + 1

=> 1

Step-by-step explanation:

this is the correct explanation of this question.

Answer 2

by applying remainder therom we'll get,

= x + 1 =0

= x = - 1

By replacing x by – 1

= x4 + 3x3 + 3x3 + x + 1

=  (-1)4+ 3(-1)3 + 3(-1)2 + (-1) + 1

=  1 -3 + 3 - 1 + 1

= 1    ( Ans)
