And why does it matter? Why are we doing this? He just did this in his head? And why? I got lost at the first line. 3x2 - 3x2 = 0 right? How can 7/2 be equal to 7-0? Also, what has this to do with long division? How is the remainder 2x+6 and the quotient x? I didn't see any division. What do...

What do you mean the most significant term and why does it matter here? Google returned nothing useful: https://www.google.ie/search?q=most significant term How do the previous things lead to this conclusion? Also, what do you mean a/b x^(n-m)? Do you mean a divided by the rest, or do you mean...

I don't understand what you mean by this sentence That's what it said in the video but I don't understand why it works.

Been away from this thread for a while because I gave up. I'm going to try again. All that came up when I googled that was some crazy stuff like this: I don't understand any of that and hence I don't understand sequential approximation. I think this is similar to a set of videos I saw called...

I was taught how to do long division in school but I don't understand it even after watching 5-10 videos and reading about it now. Like in this video: You put 8 in the 10s place. That implies it's 80 yes, but it's not 80 as we can see when it's finished. So why leave out the 6? It's 86, not...

I don't get how talking about factoring led to the long division way.

What do you mean reasonably close? If I divide 12 by 6 I don't divide 12 by 5 because 5 is reasonably close to 6. How is it a 'partial answer'? I don't get it.

Yeah I still don't understand your explanation.

I don't get it... What do you mean comparing the highest order terms at anyone time? Best guess at what? How many times x+1 goes in? Like you said, it doesn't go in x^2+x times. Whatever is left over of what where? This is so confusing and I don't get it.

Why? Isn't x+1 supposed to go in? What do you mean "how close" it is? How close it is to what? No, you divide it into 13 first and carry 2 over onto the 6. I didn't get the rest of your post. What do you mean it goes into the dividen x times? In the previous example you never mentioned a...

At first he shows 2x+4 / 2 and you just divide both 2x and 4 by 2. But then in the next example he is dividing x^2+3x+6 by x+1 and he doesn't divide x^2 by x+1, 3x by x+1 and 6 by x+1. I do not understand how he does the problem.

I don't get what you mean by this.

So you're saying that in order to understand how the equation makes the graph I have to factor it each time? I can't look at the graph and equation and understand how the 3x causes it to shift that way, right?

I don't get how it got to this and don't fully get what you mean. No, it doesn't.

I get why it's a parabola because of the x^2 (for every value of x, y is the square of that number), but why does it shift to the left (and down as well) when I add x?
