Expert Answer:

Let a, b, c be the zeroes of the given polynomial.
It is given that product of 2 zeroes is 2.
So, let ab = 2
 
Now, from the relation between coefficients and zeroes of a polynomail, we have:
Product of zeoes = -(-6) / 2 = 3
So, abc = 3
2c = 3
c = 3/2
 
Thus, the third zero of the polynomial is 3/2.
