Use the polyroots function. ... providing you need a numeric solution and not an exact symbolic solution)

But, presentation might be something of an issue. That's 40^4 results each with 3 values ... how do you intend to organize their display?

Is this the modern-day equivalent of writing "I must not talk in class" a thousand times on the blackboard?
