This dissertation measures an inclusive branching fraction of (13.9 {plus minus} 2.0{sub {minus}2.4}{sup +2.1})% for the decay {tau}{sup {minus}} {yields} {nu}{sub {tau}}{pi}{sup {minus}}{pi}{sup 0} + nh{sup 0}, where h{sup 0} is a {pi}{sup 0} or an {eta} and n {ge} 1. The data sample, obtained with the TPC detector facility at PEP, corresponds to an integrated luminosity of 72 pb{sup {minus}1} at 29 GeV center of mass energy. The measured value for this branching fraction is somewhat greater than the theoretical prediction and, taking errors into account, resolves the present difference between the inclusive and the sum of the exclusive {tau}{sup {minus}} branching fractions into one charged prong. In addition, a lower limit of 8.3% (95% CL) is placed on the branching fraction B ({tau}{sup {minus}} {yields} {nu}{sub {tau}}{pi}{sup {minus}}{pi}{sup 0}{pi}{sup 0}).
