Herein we consider a novel theme of analytically and geometrically constructing lines and circles through which complex roots of real quadratic, cubic, and quartic polynomial functions and special functions of higher degree can be located. When formulas are used, they are constructed using only values that are easily observed by secondary students from the graph. To engage the reader in this investigation and illustrate how students can experientially learn the material, this article contains dynamic graphing applets.
