Tartaglia's Formula in Action and Numbers of the form a+b√5

[@proof6930]

Its nice to see material of this type. Most people explain how the formula is derived, but never cover the issues that arrive when trying to use the fo rmula. Showing how to solve for simplified solutions to nested roots is helpful in understanding how to use the formula.
