Expert Answer
It is given that a and b are zeros of polynomial f(x)=x2-2x+3.
Therefore, a+b=2
ab=3
Now, the zeroes of the required quadratic polynomial are 
Sum of roots = 
Similarly, we get Product of roots = 1/3
Similarly, we get Product of roots = 1/3Now, the required quadratic polynomial is given by:
x2 - (Sum of roots)x + (Product of roots)
i.e., x2 - (2/3)x + (1/3)
