Book excerpt: We present preliminary results of searches for charged B mesons decaying into the charmless three-body final states h{sup ±} h{sup {-+}} h{sup ±}, where h = [pi] or K, using 51.5 fb−1 of data collected at the [Upsilon](4S) resonance with the BABAR detector at the SLAC PEP-II asymmetric B Factory. No assumptions are made about intermediate resonances. We measure the branching fractions [Beta](B{sup ±} 2!K{sup ±} [pi]{sup {-+}} [pi]{sup {+-}}) = (59.2 {+-} 4.7 {+-} 4.9) x 10−6 and [Beta](B{sup {+-}} 2!K{sup {+-}} K{sup {-+}} K{sup {+-}}) = (34.7 {+-} 2.0 {+-} 1.8) x 10−6, where the first error is statistical and the second error is systematic. In the same study, we do not observe significant signals for the final states B{sup {+-}} 2![pi]{sup {+-}} [pi]{sup {-+}} [pi]{sup {+-}} and B{sup {+-}} 2!K{sup {+-}} K{sup {-+}} [pi]{sup {+-}}, and therefore provide the 90% confidence upper limits [Beta](B{sup {+-}} 2![pi]{sup {+-}} [pi]{sup {-+}} [pi]{sup {+-}})
