Cubic equation - Wikipedia
Gerolamo Cardano is credited with publishing the first formula for solving cubic equations, attributing it to Scipione del Ferro and Niccolo Fontana Tartaglia. The formula applies to depressed cubics, but, as shown in § Depressed cubic, it allows solving all cubic equations.
Solving Cubic Equations (solutions, examples, videos)
In these lessons, we will consider how to solve cubic equations of the form px 3 + qx 2 + rx + s = 0 where p, q, r and s are constants by using the Factor Theorem and Synthetic Division. The following diagram shows an example of solving cubic equations.
Cubic Equation - Art of Problem Solving
Also, if you select for the first equation and for the second (or vice versa--they lead to the same number), you will always get a real number. One last piece of advice: Don't try to memorize this. Memorize the process (shortcut: just look at TLDR for each section).
