2015-05-11 13:36:30 +0200 | asked a question | Demonstrating Cubic Formula to a Student I'm trying to demonstrate the Lagrange approach to solving a cubic to a student. After expanding I would like to treat When simplifying, I would like it to collect all coefficients of powers of Or -- is there some other way to do this? Specifically, at least for the sake of readability, I would like to the roots to be represented only by |
