Step-by-step explanation:
Answer:

Step-by-step explanation:
Given that alpha and beta be conjugate complex numbers
such that frac{\alpha}{\beta^2} is a real number and alpha - \beta| = 2 \sqrt{3}.
Let

since they are conjugates


Imaginary part of the above =0
i.e. 
So the value of alpha = 
Its basically just subtracting from one another
for example, 6-6 is 6
or -4-3= 7
They are not congruent. Hope this helped!
