The zeros of the polynomial are given as 3−√35 and 3+√36. So,
α=3−√35 and β=3+√36
The quadratic equation is of the form,
x2−(α+β)x+αβ=0
x2−(3−√35+3+√36)x+(3−√35)(3+√36)=0
x2−⎛⎜⎝6(3−√3)+5(3+√3)30⎞⎟⎠x+(3−√3)(3+√3)30=0
30x2−(18−6√3+15+5√3)x+(9−3)=0
30x2−(33−√3)x+6=0
Therefore, the required quadratic polynomial is 30x2−(33−√3)x+6=0.
