  We introduce the notion of resultant of two planar curves in the tropical
geometry framework. We prove that the tropicalization of the algebraic
resultant can be used to compute the stable intersection of two tropical plane
curves. It is shown that, for two generic preimages of the curves to an
algebraic framework, their intersection projects exactly onto the stable
intersection of the curves. It is also given sufficient conditions for such a
generality in terms of the residual coefficients of the algebraic coefficients
of defining equations of the curves.
