## burhan101 3 years ago Help me solve this using long* division

1. burhan101

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

I hope it helps!

4. burhan101

i have questions about the method tho

5. jankiz

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

6. burhan101

oh so you factor before dividing ?

7. jankiz

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

8. burhan101

so divide using synthetic then divide the long way :S

9. jankiz

Yes!

10. jankiz

Did you get it?

11. burhan101

nooo, i just got more confused

12. jankiz

Wait a sec, let me ask my teacher.

13. burhan101

14. jankiz

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

15. burhan101

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

16. jankiz

Ohhh!

17. burhan101

yesss

18. jankiz

Are you still there?

19. burhan101

yes i am :)

20. jankiz

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

21. burhan101

okay, i hope so tooo !

22. jankiz

Is this question from a quiz or homework, is it emergence?

23. burhan101

well i have a test tomorrow and this is one of the review questions

24. jankiz

Okay!

25. burhan101

:)

26. jankiz

Still waiting!

27. jankiz

The teacher did not repy yet, I am sorry.

28. burhan101

29. jankiz

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

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. burhan101

i dont kooow :S

32. satellite73

33. satellite73

unless you are working with negative exponents, which i doubt

34. burhan101

really ? :S im pretty sure you can
