Abstract
We verify a conjecture of Emil Artin, for the case of a Cubic and Quadratic form over any -adic field, provided the cardinality of the residue class field exceeds 293. That is any Cubic and Quadratic form with at least 14 variables has a non-trivial -adic zero, with the aforementioned condition on the residue class field. A crucial step in the proof, involves generalizing a -adic minimization procedure due to W. M. Schmidt to hold for systems of forms of arbitrary degrees.
