Quadratic Equation fails when given a correct solution #82

Thanks for your work on this website! It's been fun to work through.

Just wanted to report that I'm getting a "Wrong" message on Quadratic equation, even though the answer I've given is identical to the expected answer. See attached screenshots:

I found it's due to the fact that I wasn't explicitly printing the '-' in front of a negative imaginary component, but rather allowed the printf function to automatically add the sign when the imaginary component was negative. Explicitly printing a hyphen instead got my submission accepted.

Must be that a different character is used to represent unary negation.
