In fact, on some problems, solve just never terminates, but numerical methods like roots are blazingly fast. Again, understanding what problem you are solving and the methods involved is crucial. The nature (real or not, distinct or not) of the roots of a cubic can be determined without computing them explicitly, by using the discriminant. The discriminant of a polynomial is a function of its coefficients that is zero if and only if the polynomial has a multiple root, or, if it is divisible by the square of a non-constant polynomial. In other words, the discriminant is nonzero if and only if the polynomial is square-free.
