We study analytically the branching ratio (BR) and charge parity (CP) asymmetries of the <(B-8(0))over bar> -> K*(0)rho(0) and K*(0)omega decay modes within QCDF approach. We find the BR(<(B-8(0))over bar> -> K*(0)rho(0)) = (1.28 +/- 0.23) x 10(-6) and BR(<(B-8(0))over bar> -> K*(0)omega) = (1.12 +/- 0.58) x 10(-6). We also find the values of CP asymmetries are A(CP)(dir)(<(B-8(0))over bar> -> K*(0)rho(0)) = 0.214 +/- 0.087, A(CP)(mix)(<(B-8(0))over bar> -> K*(0)rho(0)) = 0.377+0.147, A(CP)(Delta Gamma)(<(B-8(0))over bar> -> K*(0)rho(0)) = 0.901 +/- 0.051, A(CP)(dir)(<(B-8(0))over bar> -> K*(0)omega) = 0.284 +/- 0.038, A(CP)(mix)(<(B-8(0))over bar> -> K*(0)omega) = 0.835 +/- 0.024, and A(CP)(Delta Gamma)(<(B-8(0))over bar> -> K*(0)omega) = -0.471 +/- 0.063. The reported results are consistent with the recent theoretical predictions and can be used as a reference values in the forthcoming experiments.
