Abstract: If two polynomials $ F$ and $ G$ satisfy the Jacobian condition and the Newton polygon of $ F$ has an edge of negative slope, then the sum of terms of $ F$ along this edge has at most two distinct irreducible factors and their exponents must be different. Moreover, the slope is either a (negative) integer and the edge touches the $ y$-axis or a (negative) Egyptian fraction and the edge touches the $ x$-axis. Furthermore, there is an elementary automorphism which reduces the size of the Newton polygon.
