Given:-[ Factor]
x-2=0
x=2
ACCORDING TO QUESTION:-
3x²+4x+2k=-2
Now putting the value of in Given Equation (Polynomial)
3x²+4x+2k=-2
3(2)²+4(2)+2k=-2
3(4)+8+2k=-2
12+8+2k=-2
20+2k=-2
2k=-2-20
2k=-22
k=-22/2
k=-11
Thanks!!!!!

heya here is your answer...
P(x) = 3x² + 4x +2k
given that -2 is the root of the equation
p(-2) = 3×(-2)² + 4×(-2)+2k
= 12 -8+ 2k
4+2k = 0
2k = -4
=> k = -4/2 = -2
therefore the value of k will be -2
hope it helps you
thanks
