 {3x}^{2}  - 5 = 0 \\  {3x}^{2}  = 5 \\   {x}^{2}  =  \frac{3}{5}  \\ x =   \sqrt{ \frac{3}{5} }  \:  \: or \:  \:  -   \sqrt{ \frac{3}{5} }  \\  \\ their \: reciprocals \: are \\  \\ x =  \sqrt{ \frac{5}{3} }  \: or \:  -  \sqrt{ \frac{5}{3} }  \\  \\ sum \: of \: roots \: is \: 0 \\  \\ product \: of \: roots \: is -  \frac{5}{3}  \\ so \: polynomial \: having \: roots \: given \: is \:  \\  \\  p(x) =  {x}^{2}  -  \frac{5}{3}  \: or \: p(x) =  {3x}^{2}  - 5
