Question

determine whether X+2is a factor of x^9-2^9​

Answer 1

Answer:

No

Step-by-step explanation:

Put x = -2

$x^9 - 2^9 = (-2)^9 - 2^9 = -2^9 - 2^9 = - 2^{10} \neq 0$

if x+2 was factor then x = -2 should be root for polynomial

Answer 2

Answer:

No

Step-by-step explanation:

x +2 =0

x = -2

put the value of x

x^9 - 2^9

(-2)^9 - 2^9

(-512) - 512

= -1024

So x +2 is not a factor of x^9-2^9
