Question 224723: can the solution of a quadratic equation with integer coefficients include one real and one imaginary number? why and why not?

You can put this solution on YOUR website! No, because complex roots always occur in pairs.
When the Discriminant is <0, there are 2 complex roots, other terms, + and minus the sqrt of the Discriminant.
