Answer:
The other zero is also irrational. ( the complex conjugate of the first zero)
Explanation:
We are given a quadratic equation as:

where a,b and c are rational numbers.
Also it is given that the quadratic has 2 distinct zeros and one of it's zero is irrational.
" We know that for a polynomial equation with rational coefficients if it has one irrational zero then the conjugate pair of that zero is also an zero of the same polynomial equation "
Hence, in this case it is a quadratic equation such that one of it's zero is irrational, hence the other zero is also irrational.
