## anonymous 4 years ago Help me solve this using long* division

1. anonymous

$x^3-x^2+2x+1 / x^4-7x^3+2x^2+9x$

I hope it helps!

4. anonymous

i have questions about the method tho

5. anonymous

I think you do it like this, you factor both sides as much as you can then you divide.

6. anonymous

oh so you factor before dividing ?

7. anonymous

I guess so. So, factor both sides using synthetic division and then divide.

8. anonymous

so divide using synthetic then divide the long way :S

9. anonymous

Yes!

10. anonymous

Did you get it?

11. anonymous

nooo, i just got more confused

12. anonymous

Wait a sec, let me ask my teacher.

13. anonymous

14. anonymous

I did, let's wait a little bit. Is it algebra?

15. anonymous

this is advanced functions (grade 12) & yes we're solving this algebraically

16. anonymous

Ohhh!

17. anonymous

yesss

18. anonymous

Are you still there?

19. anonymous

yes i am :)

20. anonymous

Okay, my teacher replies fast. Hopefully, he will do so this time as well.

21. anonymous

22. anonymous

25. anonymous

:)

26. anonymous

Still waiting!

27. anonymous

The teacher did not repy yet, I am sorry.

28. anonymous

29. anonymous

He did, said use synthetic division to simplify and then solve.

30. anonymous

i also have a question how can you divide a polynomial of degree 3 by a polynomial of degree 4? like dividing $$\frac{1234}{12345}$$

31. anonymous

i dont kooow :S

32. anonymous

33. anonymous

unless you are working with negative exponents, which i doubt

34. anonymous

really ? :S im pretty sure you can
