complex number maths question?
(1)- express A in the form of p+qi
(2)- for what value of a is Ā / 2i = a w
help me understand how to solve this one, show every step from no.2
thanks very much
w is just a letter..

(1) Just multiply:
A = 2 + i - 6i +3 (in the last term used i.i = -1)
A = 5 - 5i
(2) The conjugate of A is ; Ā = 5 + 5I and than:
(5 + 5i)/2i =
(multiply by i
(5 + 5i).i/-2 =
(5i - 5)/-2 =
5/2 - (5/2).i
Mathematics is no sorcery: I don't have any idea what "a w" means.
