6 {x}^{2}  + 7x - 3

so,

 \alpha  +  \beta  =  \frac{ - 7}{6}  \\  \alpha  \beta  =  \frac{ - 3}{6}

so, Sum of new zeros

 \frac{1}{ \alpha }  +  \frac{1}{ \beta }  =  \frac{ { \alpha}^{2} +  { \beta }^{2}  }{ \alpha  \beta }  =  \frac{ {( \alpha  +  \beta )}^{2}  - 2  \alpha \beta }{ \alpha  \beta } \\  \frac{ {( \frac{ - 7}{6}) }^{2}  - 2  \times  \frac{ - 3}{6} }{ \frac{ - 3}{6} }  =  \frac{ \frac{49}{36}  + 1}{ \frac{ - 3}{6} }  =  \frac{ \frac{85}{36} }{ \frac{ - 3}{6} }  =  \frac{85 \times 6}{36 \times ( - 3)}  \\  \frac{ - 85}{18}

Product of new zeros

 \frac{1}{ \alpha }  \times  \frac{1}{ \beta }  =  \frac{1}{ \alpha  \beta }  =  \frac{1}{ \frac{ - 3}{6} }  =  - 2

so, new polynomial is

 {x}^{2}  - ( \frac{1}{ \alpha }  +  \frac{1}{ \beta } )x +  \frac{1}{ \alpha  \beta }  \\  \\  {x}^{2}   +  \frac{85}{18} x - 2

Hope this will help you
