3. myininaya

2x(3x)=?

4. itstito14

6x^2

5. myininaya

good now as a second step we will do the outer part which is 2x(3)|dw:1402530668986:dw|

6. itstito14

6x

7. myininaya

8. itstito14

-9x

9. myininaya

awesome now the last part is to multiply -3(3) |dw:1402530787631:dw|

10. itstito14

-9

11. myininaya

now we will just add all the terms you just told me together which is 6x^2+6x-9x-9 And you would be done if you didn't have like terms but you do

12. myininaya

so combine the like terms

13. myininaya

you only have two terms that are like terms

14. itstito14

yes

15. itstito14

36x^2

16. itstito14

for the like terms

17. myininaya

oh no.. I was talking adding 6x and -9x

18. itstito14

6x^2-3x-9

19. myininaya

you have 6x^2+6x-9x-9 the only terms that are like terms are the two terms that have the same variable part which is the term 6x and the term -9x What do you get when you add 6x and -9x? 6x+(-9x) or you could say 6x-9x or you could say -(9-6)x what is 9-6?

20. myininaya

oh you got it
