But if it had been like the above problem that method of equating the coefficients gets a little bit nasty. This is due to the fact that your idea will tend to balance the remainder in b and c. This may not be desirable.
Good mornin' bobbym!
I hope he gets it by now. This is a 5 year old thread.
Hi again Xerxes!
I don’t know the long-division method. I simply let
then expanded the right-hand side and compared coefficients.
We have to show our work using long division. No whole number times 2 gives you 3. Do you just use a fraction down in the long division work? This is where I am confused.
Yes, I know the answer from the back of the book, but I don't see how to get the answer. I need the work
Yeah, I can divide by a binomial fine, but can't do the trinomial. In this specific example, nothing times 2 gives you 3. Not a whole number, anyway. That's where I am stuck. I have the answer, but don't see where it's coming from.
What you want to do is polynomial division. Basically the overall view is that you teach each component (ax^n) as a different digit and the rest follows like normal division. Follow the steps in this link, and feel free to ask questions if you don't understand part of it.
The problem is
So far, the work I have is:
I'm stuck here, as I don't know what to do with the 2 to get
