(a)
, other zero
(b)
, other zero
(c)
, other zero
(d)
, other zero
Correct answer: (c) 
Solution: 
We know that for a quadratic polynomial ,
product of the zeros=
Here,quadratic polynomial is
One root is  
Let the other root be
Therefore,
Therefore,
The other zero is
Also, sum of the zeros =
Therefore,
, other root
