Question

Factor completely: 9c3d2 − 6cd3

3cd2(3c − 2d)

3cd(3c2 − 2d2)

3c2d(3c − 2d2)

3cd2(3c2 − 2d)

Answer 1

what do they have in common?

Answer 2

2 - 2d

Answer 3

meaning...what can you take out of both sides? are both 6 and 9 divisable by 3?

Answer 4

no idea

Answer 5

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?

Answer 6

i meant "c" sorry

Answer 7

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?

Answer 8
