Here given, One root is = 0

So others root which are reciprocal =

$\alpha \: \: \: and \: \: \frac{1}{ \alpha }$

Now, sum of three roots =

$\alpha + \frac{1}{ \alpha } + 0 = - \frac{b}{a} \\ \implies \: \alpha + \frac{1}{ \alpha } = - \frac{b}{a}$

So,

the sum of the reciprocal of the others two zeroes is =

$\alpha + \frac{1}{ \alpha } = - \frac{b}{a}$
