Answer 2

Answer:

k = -5

Step-by-step explanation:

x^3 + (k+8)x + k

let first x be =2

to find the first remainder

:- 2^3 + (k+8)2 + k

=> 8 + (k+8)2 + k

= 24 + 3k

let second x be = -1

=> R2 = (-1)^3  + (k+8)-1 + k

-1 + (k+8)-1+k

= -9 -k+k

=-9

since, R1+R2=0

∴ 24+3k-9 = 0

3k = -15

∴ k = -5
