Answer 4

This sounds like such a ridiculous amount of work.
First find out if you have multiple roots or not by calculating the greatest common divisor of your polynomials. If x = 1, then you have no multiple roots and you can use a simpler equation. It's still algorithms though, which are kind of out of my league.
