Line OQ is angle bisector of angle O of right angle triangle OPR , right angle at P . Point Q is such that ORQP is concyclic. If point O is orign and points P,Q,R are represented by the complex numbers z_(3),z_(2),z_(1) respectively. If (z_(2)^(2))/(z_(1)z_(2))=3/2 then ( R is circum radius of /_\OPR )
