Answer:

K= 2

Step-by-step explanation:

P(-2) = 3(-2)^2 + 4(-2) +2K

= 12 - 8 + 2K

= 4 + 2K

- 4 = 2K

- 4/2 = K

SO, K = - 2

Answer:

k= -2

Step-by-step explanation:

Given polynomial:

p(x) = 3x2 + 4x + 2k..

as, x= -2,is a root of the polynomial so, p(-2)..shall satisfy the given polynomial..

therefore,p(-2)=0

3(-2)^2+4(-2)+2k=0

3×4-8+2k=0

12-8+2k=0

4+2k=0

2k=-4

k=-2(ANS)...
