## frecy 2 years ago a^3-3a^2-a+20 ; a+20 "The remainder Theorem"

1. Skaematik

...and?

2. frecy

this is how it goes |dw:1351596490872:dw|

3. Skaematik

You wanted it divided?

4. frecy

yup

5. hba

Lets me give you an example x^2+2x+x+1,a+1|dw:1353324316706:dw|

6. irkiz

Is it a must to solve by long division?

7. hba

This is Remainder theorem ^^

8. hba

No we have to solve it by remainder theorem,not by long division

9. Skaematik

So what is the question

10. hba

We have to solve it using Remainder theorem ?

11. hba

@frecy You see my example can you solve your ques ?

12. hba

@frecy You there ?

13. hba

lol I won't . After long division, Let f(a)=a^3-3a^2-a+20.

15. hba

But we have to solve it by Remainder theorem dude .

16. hba

Do you see my example ?

She isn't really specific about whether she wants to show the remainder theorem or that she wants to know what is f(20)=remainder.

18. hba

@Shadowys Well the ques says Remainder theorem :D

19. hba

After solving the remainder theorem we can solve it

20. hba

Anyways if @frecy Does not respond , she is not going to get help :)

21. Skaematik

You don't really know what the question is dude.

Yh...lol cause, by the looks of it, then I'll just let f(a) and sub a=-20 lol

23. hba

Yeah LD

24. hba

@Skaematik Nice Joke...

25. Skaematik

OK have fun wasting your time trying to help her

26. hba

We have got a bad-retricein here ^

28. hba

Haha :P

29. frecy

sorry guys. theres an emergency happened. sorry. please go on.

30. frecy

It must be solved by long division.

31. hba

Then why did you write "remainder-theorem'' ?

32. hba

Moreover you should try to solve it and we are gonna see whether you do it write or wrong.If you do not know how to really solve it we can put up some examples for you :)

33. Skaematik

Haha @hba

34. hba

right*

35. frecy

thats what my teachers said. but i know that should be solve using long division

36. irkiz

that was why i was confused. In the first part she said remainder theorem. then after that she put it into a long division :)

37. hba

@frecy Do you know what remainder theorem is ?

38. hba

Do you even know how to solve using remainder theorem ?

39. frecy

sorry guys. can you please just help me solving it by long division?

40. hba

@Skaematik Please do not give direct answer,just show her an example or you will violate the CoC- http://openstudy.com/code-of-conduct and may be reported or banned.

42. frecy

i'll try to solve it but help me to correct what's wrong in my solution. is that okay?

43. Skaematik

44. hba

@frecy Sure.

okay thanks!
