I divided (-4x^3 + x^2 - 4)/(x - 1) and got a totally different answer on three attempts than the book.

Here is the right answer:

-4x^2 - 3x - 3 remainder -7

How can this be?

Can you show mestep by stepwhy the above answer is correct?

Hello,

My method may not be like yours, but I can't manage to change it ~~

and x-1.

First, I see the first term of the polynomial -4x^3 and the first term of x-1 : x.

.

So I'll write :

And so on... :

If you want to know where your mistake(s) is/are, just show your work ^^ - August 26th 2008, 09:52 PMmagentaritaPerfect!
