Question

x+1 /x3 + x2 + x + 1 find the factor of polynomial​

Answer 1

Answer:

Here

on putting x + 1 = 0, we get x = -1

put x = -1 in p(x) we get

(-1)cube + (-1) square - (-1) + 1

= (-1) + (1) + 1 + 1

= 2

Since, we didn’t got zero ( 0 ).

Therefore, x +1 is NOT a FACTOR of given Polynomial

Answer 2

Step-by-step explanation:

$\frac{(x + 1)}{x {}^{3} + x {}^{2} + x + 1 } \\ = \frac{(x + 1)}{( {x}^{2} + 1)(x + 1)} \\ = \frac{1}{( {x}^{2} + 1) }$
