2x+1=0
x=-1/2
4×(-1/2)^2-(-1/2)k+ k
2+1/2k+k
2+1/2k+k divided by 2x+1
Rest is a linear equation which u can solve easily.

2x+1=0
x=-1/2
again
4(-1/2)^2-k(-1/2)+k=0
4×1/4+k/2+k=0
1+k/2+k=0
k+2k=-1
3k=-1
k=-1/3
is your answer
x=-1/2
again
4(-1/2)^2-k(-1/2)+k=0
4×1/4+k/2+k=0
1+k/2+k=0
k+2k=-1
3k=-1
k=-1/3
is your answer
