let the other  zero be z  then

z =  a + sqrtb      1
       ----------- * ------------
        a^2 - b     a - sqrtb

              
   =   1 / (a - sqrt b)^2

Polynomial is:-

(x - (a - sqrtb) )  ( x  -   1 / (a - sqrtb)^2))

which expands to  (a - sqrt b)^2 x^2 - (1 + (a - sqr b)^3 ) x  + a  - sqr tb
