a+b+c>=d
If a is the root of 4x+1=0 and b,c are the roots of 4x^2+3x+k=0, then greatest value of d will be

OPtion

1) 1
2) -1
3) 2
4) -3/4
5) -3
6) -4/3
7) 4
8) 3/2
9) -3/2
10) none of these

Solution

according to the given conditions a = -1/4
and b+c = -3/4
so a+b+c = -1
so greatest value of d = -1
