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...
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...
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.
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.
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 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?
