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)...
