Dalitz Plot Analysis of B^+ ->h^+h^-h^+

We present preliminary results of a maximum-likelihood Dalitz-plot analysis of the charmless hadronic B^± decays to the final states &±circ;̂&±circ;, K^±̂&±circ;, and K^±K^K^± from data corresponding to an integrated on-resonance luminosity of 211 fb^-1 recorded by the BaBar experiment at the SLAC PEP-II asymmetric-energy B Factory. We measure the total branching fractions and asymmetries and provide fit fractions, fit fraction asymmetries and phases for the intermediate resonance states.
