The centre of circle represented by `|z + 1| = 2 |z - 1|` in the complex plane is

If the real part of (z+2)/(z-1) is 4, then show that the locus of he point representing z in the complex plane is a circle.

If the real part of (z +2)/(z -1) is 4, then show that the locus of he point representing z in the complex plane is a circle.

If the imageinary part of ( 2z+1)/( I z +1) is -2 then the locus of the point representing z in the complex plane is

If the real part of frac{bar z + 2}{bar z -1} is 4, then show that the locus of the point representing z in the complex plane is a circle.

If the imaginary part of frac{2z+1}{iz+1} is -2 , then the locus of the point representing z in the complex plane is
