Ok, let me start by saying that I know how to do polynomial long divison. At least I thought I did. But, I've encountered one that's giving me trouble.
I'm new to formatting this stuff on the web, but so far, I've gotten as my quotient, with still left to be divided.
The problem is that I don't see how you can divide into .
Am I missing something?
I can attempt to format the work I've done thus far, but I'm hoping that won't be necessary. If it is, can anyone give me an example of how to format long division on here?
Thanks or the reply, but that doesn't make a bit of sense to me.
That isn't something that we've covered at all.
Also, I've been to that site, as well as purplemath. Every example they give, the factor divides evenly every time.
I can do those, no problem. It's this one that's giving me grief.
Well I think this example is a good one. In your case you need to deal with some fractions and maybe that's what is giving you a hard time.
First compare the leading terms of each expression Take that result and multiply it through the divisor.
and subtract this from the original dividend.
What do you get?
First, thanks for the help.
Second, that confuses me even more.
If I were to do that ( ), I'd end up with
I just don't see how you came up with:
I posted a pic of what I have so far on the problem I posted about, as well as a similar problem that's also giving me trouble.
Thanks for the link, but it still doesn't tell me how to get the answer.
I could just just plug the answer in for a correct answer (this is from my online homework), but that's not what I'm after.
If I don't understand the concepts, the answers aren't going to do squat for me.
The problem is, this is on my homework. It's nothing we've covered, but it's due tomorrow night. And, with it being fall break on campus, there is no one here to talk to about it.
I've already emaild my prof regarding the lack of instruction on this type of problem, but haven't yet received a response.
So, without a response, and with it being due tomorrow night, it's up to me to understand it and do it by then.
I should've been more clear. I understand cancelling out exponents/variables within a fraction.
I guess what I'm not so clear on is when do you know you'll have to do a step like that?
Would you need to do something like this when you're left with a leading coefficient on the variable of the dividend that's smaller than the leading coefficient in the divisor?
cannot divide evenly into , so would this ALWAYS tell me to do the problem as discussed? Or is there some other circumstance that should tell me to divide only the leading dividend variable by the leading divisor variable?
I hope all that made sense. I was having trouble making sense of it myself as I was typing it.
BTW, thanks for all the help thus far.
When you look at a problem like this, you have to ask yourself: "What when multiplied by will give me . Since 3 is not a divisor of seven, you know that there will be a fraction involved. So we have:
Thus, we come to the conclusion that the first term of the coefficient is:
Continue the problem as such, and you will arrive at the answer.
