Answer 1

Step-by-step explanation:

Any quadratic equation can have: 2 solutions, if the discriminant (number inside the root) is greater than zero; one solution, if the discriminant is zero; no solution, if the discriminant is negative. If we are working in the universe of complex numbers, then the second-degree equation always has at least one solution.
