Question
If z = x + i y then the equation of a straight line Ax + By + C = 0 where A, B, C ∈ R, can be written on the complex plane in the form 
= 0 where ′a′ is equal to :
= 0 where ′a′ is equal to :Options
A.
B.
C.A + i B
D.none
Solution
A 
+ C = 0 ⇒ 
+ C = 0 ⇒ z(A - iB) + 
(A + iB) + 2C = 0
+ C = 0 ⇒ + C = 0 ⇒ z(A - iB) + (A + iB) + 2C = 0Create a free account to view solution
