Answer
$18$, $-15i$, $12i$, $-10i^{2}$, $10$
Work Step by Step
Consider the following multiplication problem:
$(3+2i)(6-5i)$
Using the FOIL method, the product of the first terms is $18$, the product of the outside terms is $-15i$, and the product of the inside terms is $12i$. The product of the last terms in terms of $i^{2}$ is $-10i^{2}$, which simplifies to $10$.
This is mentioned on page 139.
