Hi, Travis,

I assume you already tried to find rational roots, so you will have to use 'Cardano's Formula', which you will find at various places, such as:

en.wikipedia.org/wiki/Cubic_equation

It is a lot of work, which is why I'll let you do it.  I've never actually done it myself, nor do I know anyone who did.

Expertise

I can answer questions in basic to advanced algebra (theory of equations, complex numbers), precalculus (functions, graphs, exponential, logarithmic, and trigonometric functions and identities), basic probability, and finite mathematics, including mathematical induction. I can also try (but not guarantee) to answer questions on Abstract Algebra -- groups, rings, etc. and Analysis -- sequences, limits, continuity. I won't understand specialized engineering or business jargon.

Experience

I taught at a two-year college for 25 years, including all subjects from algebra to third-semester calculus.
