We report on a study of three-body charmless decays B+→K+h+h- based on a 29.1 fb-1 data sample collected with the Belle detector. With no assumptions on the intermediate mechanisms, the following three-body branching fractions have been measured for the first time: B(B+→K+π-π+)=(55.6±5.8±7.7)×10-6 and B(B+→K+K-K+)=(35.3±3.7±4.5)×10-6. We present the first observation of the decay B+→f0(980)K+ with a branching fraction product of B(B+→f0(980)K+)×B(f0(980)→π+π-)=(9.6-2.3-1.5-0.8+2.5+1.5+3.4)×10-6. This is the first reported example of a B meson decay to a scalar pseudoscalar final state. We also report the first observation of B+→K*(892)0π+ decay with a branching fraction of B(B+→K*(892)0π+)=(19.4-3.9-2.1-6.8+4.2+2.1+3.5)×10-6.
