    Is this what you mean?

    x=0, solution = 160,000
    etc ...

    let y=x^2 and then go here

    it's a university level topic, I was never introduced to it in class.

    It is so old that I would be astonished if one ever encountered it in a university mathematics class, even in graduate school.

    There is not much point beyond showing how one might solve a quartic equation by radicals. There is very little reason to do this in practice.

    What you would see in an advanced university class is a development of the theory of fields, Galois theory. In Galois theory it is proved that the general quintic and higher polynomial is not solvabe by radicals.
