Explanation:
The complex conjugate or conjugate of a complex number
A useful property of the complex conjugate is that for any complex number
We use this property by multiplying the numerator and denominator of the expression by the conjugate of the denominator. This results in a real-valued denominator when we can then distribute (if necessary).
#=(12i-6i^2)/(16+8i-8i-4i^2)#
#=(12i-(-6))/(16-(-4))#
#=(6+12i)/20#
#=3/10 + 3/5i#
