    The General form of a quadratic polynomial whose Sum of roots and products of roots is given :

    x2- ( Sum of roots) x + ( Product of roots ) =0

    In the above question,
    Sum of roots =√2​
    Product of roots =1/3.

    Now, The quadratic polynomial
    x²−√2​x+1/3=0
    3x²−3√2​x+1=0

    Required polynomial is 3x²−3√2​x+1
