Question

determine which of the following polynomial has (x+1) a factor (i) x4+3x3+3x2+x+1​

Answer 1

Step-by-step explanation:

x+1=0

x=-1

x^4+3x^3+3x^2+x+1

(-1)^4+3(-1)^3+3(-1)^2+(-1)+1

1-3+3-1+1=0

so,x+1 is the factor of given polynomial.

Answer 2

Answer:

p(x) =x4+3×3+3×2+x+1

=(-1) 4+9+6+(-1) +1

=-4+15-1+1

=-4+15

=11
