Answer 1

Answer:

x + 1 is a factor ;

then ;

x + 1 = 0

x = -1

1) x^3 + x^2 - x + 1

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

= -1 + 1 + 1 + 1

= 2

2 ) x^3 + x^2 + x + 1

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

= - 1 + 1 - 1 + 1

= 0

so the correct answer is optionB ))....

Answer 2

Answer:

X = - 1

Now try putting the value of x in each of the option.......

After solving option b... U will get to know that's the answer comes zero

So the option will be the factor of x + 1
