    anything else is given ?? say P have co-ordinates (x,y). Then you may take, A or B as origin, and apply distance formula to get PA and PB....

    hartnn mean that take P(x,y) n i think u r provided wid coordinates of A and B apply distance formula to get equation of locus of the point P

    you know distance formula, right ? Distance between points (x1,y1) and (x2,y2) is \(\huge d=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}\)
