Full solution stays hidden until you ask for it.
1. Use discriminant sign to classify root type.
2. For zero discriminant, count the repeated root twice by multiplicity.
3. State the total complex root count for a quadratic is 2.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Saying zero discriminant gives only one root counting multiplicity.
