\(x^{2}+1=0\)
We are taught early that there is no solution to this equation. What was meant is that the is no real solution. x=(0+i) is the complex solution.
I once used that "fact" to program a random number generator, based on using Newton's Method to solve this equation and truncating the results as a seed back into the system.
Worked pretty well, but if you were to ask me today "why", I couldn't answer you. Perhaps as a challenge, some people here could examine the algorithm?
