jstod i belive u are getting [(75/4)-33.88860428i] and[(75/4)+33.88860428i]. scary init?...lol. don't be scared; they are complex roots of the equation. these are numbers dat were believed to be inexistent back in the day until a German mathematician Carl Friedrich Gauss foun a way to integrate them into the real number system and so represented them in the form (a+bi).
