Q.) The roots of the equation will be reciprocal to each other if the value of a is

1)3

2)4

3)5

4)6

Solution :

The product of the roots in the quadratic equation is given by

product of the roots =

Let the roots of the equation be and (as they are reciprocal to each other)

Product of the roots =

=> X =

=> 1 =

=> a = 6.

Hence , Option(4)
