Walkthrough
Full solution stays hidden until you ask for it.
1. Check whether the discriminant is positive, zero, or negative.
2. Positive gives two real solutions; zero gives one repeated real solution.
3. Negative gives two non-real complex conjugate solutions.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Saying negative discriminant means no solutions in the complex number system.
