Answer:
-16 - 30i
Step-by-step explanation:
(3-5i)^2 = (3-5i) * (3-5i)
Applying the "FOIL" method of expanding this expression through multiplication, we get:
9 - 15i - 15i - 25    (since i^2 = -1)
Simplifying this result, we get -16 - 30i
 
        
             
        
        
        
The answer would be the following:
9 x - 4 = 4x + 16
