" 11.If "Re((z+4)/(2z-1))=(1)/(2)," then "z" is represented by a point "

Re((z+4)/(2z-1))=(1)/(2), then z is represented by a point lying on

Re((z+4)/(2z-1)) = 1/2 , then z is represented by a point lying on

(1) Re((z1z2)/(barz1))

If Re((z-1)/(2z+i))=1, where z=x+iy ,then the point (x,y) lies on a

Let z_(1) and z_(2) be two non-zero complex numbers such that (z_(1))/(z_(2)) + (z_(2))/(z_(1)) = 1 , then the origin and points represented by z_(1) and z_(2)

The curve represented by Re(z^(2))=4

If z ne 1 and (z^(2))/(z-1) is real, then the point represented by the complex number z lies

If z_(1)&z_(2) are two complex numbers & if arg (z_(1)+z_(2))/(z_(1)-z_(2))=(pi)/(2) but |z_(1)+z_(2)|!=|z_(1)-z_(2)| then the figure formed by the points represented by 0,z_(1),z_(2)&z_(1)+z_(2) is:
