whitecorp help!

let z=x+yi
so mod(z-u)= square root of [(x+0.4)^2 + (y-2.2)^2] ---> 1
and mod of u=square root of 5 ---> 2
On equating 1 and 2 and then squaring on both sides..v get:-
(x+0.4)^2 + (y-2.2)^2 = 5
this is lyk an equation of a circle wid centre (-0.4, 2.2) and radius= square root of 5

idk...how post diagrams...
hope dis helps!
