The locus of "quadrics of cubics" inside the full projective linear system of plane sextics forms a divisor. Why should that divisor contain the entire locus of reducible curves that are unions of a conic and a quartic? Presumably one could prove that it does not by computing the Zariski tangent space of this divisor at the point parameterizing a single reducible curve that has such a representation. If the Zariski tangent space of the divisor does not contain the tangent space of the reducible locus, then we are done. | |
