Question

Explain why (2 + 3i)(2 – 3i) is a REAL number.

Answer 1

Answer: Complex Number, Real Part, Imaginary Part. 3 + 2i, 3, 2. 5, 5, 0, Purely Real. −6i, 0, − ... Example: add the complex numbers 3 + 5i and 4 − 3i ... Example: (3 + 2i)(1 + 7i) = (3×1 − 2×7) + (3×7 + 2×1)i = −11 + 23i. Why Does That Rule Work

We used the distributive property to multiply a real number by a complex number.(2 − 16i) = (5 − i)(a + bi) = 5a + 5bi −ai + b = (5a + b) +
