Hello

Given that
 \alpha  = 3 +  {a}^{2}  \\  \beta  = 3 -  {a}^{2}
Now
The relation between the coefficients and Zeroes of the polynomial are

 \alpha  +  \beta  = 3 +  {a}^{2}  + 3 -  {a}^{2}  \\  \alpha  +  \beta  = 6 \\  \\  \alpha  \beta  = (3 +  {a}^{2} )(3 -  {a}^{2} ) \\  \alpha  \beta  =  {3}^{2}  -  {a}^{4}    = 9 -  {a}^{4}
Now,

The polynomial is of the form

k( {x}^{2}  - ( \alpha  +  \beta )x +  \alpha  \beta )

So, the polynomial is
k( {a}^{2}  - 6a + 9 -  {a}^{4} ) \\
When k is 1

Hope this will be helping you ✌️
