What restrictions on the methods?

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

That is a big restriction. Then because it a cubic without a square term you can use Viète's formula.
