Factor completely: 9c3d2 − 6cd3
3cd2(3c − 2d)
3cd(3c2 − 2d2)

can 3 go into both 6 and 9 evenly? yes they can
so we can factor a 3 out.....
is there at least 1 "u" in each side?

there is at least 1 "c" in each side....there is at least 1 "d" in each side...so all can be factored out (moved out of the parenthesis)
so we have
3cd(3c²d - 2d²)
huh...look we still have at least 1 "d" in each side ...so we can factor out another "d"
3cd²(3c² - 2d)
which option choice is that?
