Hi , could someone please help with this line of working I w=3(1-w) implies w=3(w-1) I don't understand how the result is found . many thanks

thank you for your reply , sorry I omitted the modulus , it should read | i w| = 3 |1-w| implies |w| = 3 |w-1| Does this make a difference .

If each of $\displaystyle z~\&~w$ is a complex number then $\displaystyle |zw|=|z||w|$ and $\displaystyle |z-w|=|w-z|.$ Moreover, because $\displaystyle |i|=1$ it follows that $\displaystyle |iw|=|w|.$
many thanks much clearer now
