How to Find the Real and Imaginary Solutions of a Polynomial

Introduction

It has been of 4 decades since imaginary numbers. Like it wasn't hard enough with real ones. I think the basic theory is that you make everything a square too of negative 1 or $\sqrt{-1}$

So if you see $\sqrt{-2}$ This is actually +/- 2$\sqrt{-1}$ or 2i where i is an imaginary number and 2 is real
