Teach conjugates as a useful relationship

Begin with (2 + 3i)(2 − 3i). Distribution produces 4 − 9i² because the imaginary cross terms cancel. The product is 13.

Generalize the same calculation to (a + bi)(a − bi) = a² + b². Then use it to explain why multiplying both parts of a complex fraction by the conjugate gives an equivalent fraction with a real denominator.
