Evaluate: (2 + 3i)(4 - i). Write in form a+bi
Direct Answer: Complex Conjugates & Products is defined by: 11+10i. FOIL expansion: 8 - 2i + 12i - 3i² = 8 + 10i - 3(-1) = 8 + 3 + 10i = 11 + 10i.
Detailed Step-by-Step Explanation:
FOIL expansion: 8 - 2i + 12i - 3i² = 8 + 10i - 3(-1) = 8 + 3 + 10i = 11 + 10i.
