Scattering problem of the pentaquark uudds-bar system in the standard non-relativistic quark model is solved by treating a very large five-body model spapce including the NK scattering channel explicitly. Although a lot of pseudostates with J=1/2+, !/2^- and J=3/2+, 3/2^- are obtained within the bound-state approximation, all the states when the NK scattering boundary condition is imposed. Similar scattering calculation is performed for the tetraquark cc-baruu-bar system in connection with X(3872).
