Problem 150 of 7
Explain why complex numbers make quadratic any real-coefficient quadratic solvable.
Using a hint is okay. It just tells the trainer to give you a little more review.
Hidden until you reveal it.
connect negative discriminants to imaginary roots.
Hidden until you reveal it.
Prompt must concern quadratic solvability over complex numbers.

Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Use the quadratic formula as the general solution path.
2. Identify the only obstruction over reals: square roots of negative discriminants.
3. Explain that i represents those square roots over complex numbers.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Saying every quadratic has two real roots.
