Answer
First :- $18$
Second :- $-15i$
Third :- $12i$
Fourth :- $-10i^2$
Fifth :- $10$
Work Step by Step
The given expression is
$=(3+2i)(6-5i)$
Use the FOIL method.
The product of the first terms:
$=(3)\cdot (6)=18$.
The product of the outside terms:
$=(3)\cdot (-5i)=-15i$.
The product of the inside terms:
$=(2i)\cdot (6)=12i$.
The product of the last terms:
$=(2i)\cdot (-5i)=-10i^2=10$.
