Solution
The correct option is Cp−√q Given: p+√q∀p,q∈Z is one of the roots of a quadratic equation.
Now, p+√q is an irrational number whose conjugate will be p−√q.
We know, if one of the roots of a quadratic equation with rational coefficients is an irrational number, then it's other root will be it's irrational conjugate. ⇒p−√q will be the other root of the equation.
