yup

Lets me give you an example

- anonymous

Is it a must to solve by long division?

- hba

This is Remainder theorem ^^

- hba

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

- anonymous

So what is the question

- hba

We have to solve it using Remainder theorem ?

- hba

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

- hba

@frecy You there ?

- hba

@Shadowys Please do not give the answer :)

- anonymous

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

- hba

But we have to solve it by Remainder theorem dude .

- hba

Do you see my example ?

- anonymous

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.

- hba

@Shadowys Well the ques says Remainder theorem :D

- hba

After solving the remainder theorem we can solve it

- hba

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

- anonymous

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

- anonymous

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

- hba

Yeah LD

- hba

@Skaematik Nice Joke...

- anonymous

OK have fun wasting your time trying to help her

- hba

We have got a bad-retricein here ^

- anonymous

@frecy you really there? I think you've got your answer up there already lol.

- hba

Haha :P

- anonymous

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

- anonymous

It must be solved by long division.

- hba

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

- 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 :)

- anonymous

Haha @hba

- hba

right*

- anonymous

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

- anonymous

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

- hba

@frecy Do you know what remainder theorem is ?

- hba

Do you even know how to solve using remainder theorem ?

- anonymous

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

- 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.

- anonymous

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

- anonymous

go ahead

- hba

@frecy Sure.
