(a) -3

(b) 4

(c) 2

(d) -2

Please tell only right answer ​

Answer 1

Answer:

2 is the answer

Step-by-step explanation:

please make my brilliant answer

Answer 2

*answer*

(c )2

*explanation*

if x+1 is a factor of the polynomial

then x=-1 is the solution of the polynomial

now p(-1)=2×(-1)^2+k×-1

0 =2×1-k

-2=-k

2=k
