Answer 1

Answer:

This does not belong to English.

Answer 2

Hey MATE!!

For (x+1) to be a factor of the polynomial

x^3 + x^2 +x +1 , <x= -1> should satisfy the equation and resultant must be zero.

We put x = -1 in the equation;

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

=> -1 + 1 -1 +1 = 0

Hence proved that (x+1) is the factor of the polynomial.

Hope it helps

HAKUNA MATATA :))
