B{sup {+-}{yields}{pi}+{pi}-}K{sup {+-}}and B{sup 0{yields}{pi}+{pi}-}K{sup 0} decay channels are analyzed within the QCD factorization scheme where final state interactions before and after hadronization are included. The K*(892) and K{sub 0}*(1430) resonance effects are taken into account using the presently known {pi}K strange vector and scalar form factors. The weak decay amplitudes, which are calculated at leading power in {Lambda}{sub QCD}/m{sub b} and at the next-to-leading order in the strong coupling constant, include the hard-scattering and annihilation contributions. The end-point divergences of these weak final state interactions are controlled by two complex parameters determined through a fit to the available effective mass and helicity angle distribution, CP asymmetry, and K*(892) branching ratio data. The predicted K{sub 0}*(1430) branching ratios and the calculated direct CP violation asymmetries are compared to the Belle and BABAR Collaboration data.
