what do they have in common?

2. mikaa_toxica13

2 - 2d

3. johnweldon1993

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

4. mikaa_toxica13

no idea

5. johnweldon1993

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?

6. johnweldon1993

i meant "c" sorry

7. johnweldon1993

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?

8. mikaa_toxica13

ima go with the last one

9. johnweldon1993

and you are correct :) but do you understand it?

10. mikaa_toxica13
