Do 1 prob at a time

6. anonymous

-4÷4×+8

7. anonymous

= or not equal 2

8. anonymous

5X+3/4×-9

9. anonymous

Simplify them then c Wat the final anger is n that's how u solve

10. aripotta

you wanna simplify what you can, before multiplying them. 4x + 8 and x^2 - 9 can be simplified. tell me what you get once you do that

can you help?

16. geerky42

Here, you can factor 4x + 8 and x^2 - 9 Can you do that?

18. geerky42

Yeah \[\dfrac{-20(x+3)}{(4x+8)(x^2-9)}\]

19. anonymous

ok

20. geerky42

Again, can you factor 4x+8? What about \(x^2-9\)?

21. anonymous

@geerky42

22. anonymous

how do you do that?

23. anonymous

@peachpi

24. anonymous

To factor 4x + 8, you need to pick out the common factor between 4x and 8 and pull it outside the parentheses. To factor x² - 9, follow the difference of squares pattern.

25. anonymous

whould you mind showing me on the draw tool?

26. anonymous

it is easier for me to understand!:D
