Answer
$18;
\\-15i;
\\12i;
\\-10i^2;
\\10$
Work Step by Step
product of the first terms:
$=3(6)
\\=18$
product of the outside terms:
$=3(-5i)
\\=-15i$
product of the inside terms:
$=2i(6)
\\=12i$
product of the lest terms:
$=2i(-5i)
\\-10i^2$
Since $i^2=-1$, then
$-10i^2= -10(-1)=10$
Therefore, the missing expressions in the given statements, in order are:
$18;
\\-15i;
\\12i;
\\-10i^2;
\\10$
