SUMMARY
The discussion focuses on rewriting the complex number A = 1 / (-2 + 4i) using the complex conjugate method. The correct transformation involves multiplying both the numerator and denominator by the complex conjugate of the denominator, resulting in A = -(1/10) - (1/5)i. This method simplifies the expression and eliminates the imaginary unit from the denominator, showcasing a fundamental technique in complex number manipulation.
