Answer:
<h2>(2 + 2i)(5 + 3i) = 4 + 16i</h2>
Step-by-step explanation:
Use FOIL: <em>(a + b)(c + d) = ac + ad + bc + bd</em>
and i² = -1
(2 + 2i)(5 + 3i) = (2)(5) + (2)(3i) + (2i)(5) + (2i)(3i)
= 10 + 6i + 10i + 6i² = 10 + 6i + 10i + 6(-1)
= 10 + 6i + 10i - 6 <em>combine like terms</em>
= (10 - 6) + (6i + 10i)
= 4 + 16i
