Question

Divide: (7 + 4i) ÷ (2 + 3i)

Answer 1

Well for this you have\[\frac{ 7+4i }{ 2+3i }\] How do we simplify this? We need to multiply the numerrator and the denominator by the conjugate of the denominator which is basically switching the middle sign... So its 2-3i... So multiply the top and bottom by 2+3i.. Make sense?
