%0 Book Section %T Tropical conics for the layman publisher American Mathematical Society %D 2009 %U 978-0-8218-4782-4 %@ https://hdl.handle.net/20.500.14352/45378 %X We present a simple and elementary procedure to sketch the tropical conic given by a degree-two homogeneous tropical polynomial. These conics are trees of a very particular kind. Given such a tree, we explain how to compute a defining polynomial. Finally, we characterize those degree-two tropical polynomials which are reducible and factorize them. We show that there exist irreducible degree-two tropical polynomials giving rise to pairs of tropical lines. %~
