Hello :)

student
I am working on radicals
18,534

volunteer
oh good
18,534
3
[]
student
I've kind of got the gist but I have questions on certain parts
18,534
4
[]
student
l start on the board
18,534
5
[]
volunteer
i dont quite understand what problem you are stying to solve, is it square root of 39?
18,534
6
[]
student
yes
18,534
7
[]
student
from here I need to simplify but I don't know how to with out a calculator, we cant use them.
18,534
8
[]
volunteer
so, i dont think you are doing this right
18,534
9
[]
volunteer
you are separating the 36 and the 3
18,534
10
[]
volunteer
and trying to say that the squareroot of 36 is 6 and so the squareroot of 39 is 6 plus 3/12?
18,534
11
[]
student
Yes but I have to simplify it
18,534
12
[]
student
the 3/12
18,534
13
[]
volunteer
that is just 1/4
18,534
14
[]
volunteer
which is .25
18,534
15
[]
volunteer
ok so your trying to estimate what it is without a calc
18,534
16
[]
student
but how do I find that out
18,534
17
[]
student
Yes
18,534
18
[]
volunteer
ans you get 6 + .25
18,534
19
[]
volunteer
so you get 6.25 as the answer
18,534

wonderful work
18,534

student
Thanks, could we do another?

volunteer
9 + (4/18) = 9.22
18,534
24
[]
volunteer
the real root is 2.1957 so very good aproximate
18,534
25
[]
volunteer
, sorry but I have to go, im sure there is another tutor waiting to help you!
18,534

sorry, BYE!

Okay, thank you for your time

Find the derivative of f) = x \sin(x) h(x)=x2sin(x)
18,453

i can work on it

How's it going?
18,453

[]
student
h′(x)=2xsin⁡(x)+x2cos⁡(x)h'(x) = 2x\sin(x) + x^2\cos(x) h′(x)=2xsin(x)+x2cos(x)
18,453

Does that make sense?

Yes. Thank you!!!

Can you help me with Factoring completely- algebra 1

Hi!
18,500

[]
volunteer
Of course!
18,500

Thanks :)

I'll give you an example problem to go by.. can you also do a visual representation.?
18,500
5
[]
volunteer
sure!
18,500

student
on the board?
18,500

I see the image
18,500

[]
student
Thanks
18,500

So our job is to factor
18,500
10
[]
student
yes sir/maam
18,500
11
[]
volunteer
Sir 😊
18,500
12
[]
volunteer
This is a bit of a tough problem, but we can do it!
18,500
13
[]
student
okay...
18,500
14
[]
student
like factoring completely
18,500
15
[]
volunteer
yep
18,500
16
[]
volunteer
I have an idea
18,500
17
[]
student
okay....
18,500
18
[]
volunteer
Can you hear me, by the way? Can we use audio?
18,500
19
[]
student
i can't hear you..
18,500
20
[]
volunteer
hit the mute button
18,500
21
[]
student
i can hear you now... :)
18,500
22
[]
volunteer
by the chat in the blue
18,500
23
[]
volunteer
Great
18,500
24
[]
volunteer
OK, so what I'm noticing about this problem is that we can, the idea I have is we can divide it into two
18,500
25
[]
volunteer
So I'm going to use my pencil, we can kind of separate this part.
18,500
26
[]
volunteer
and this part
18,500
27
[]
volunteer
And the reason why I'm doing that is because I see we have like a 5 and a 10, which are, you know, similar, and then a 4 and an 8, which are also similar. So let's see if that um if that helps us solve the problem.
18,500
28
[]
volunteer
Do you wanna try factoring each of these separately and see if that helps us with the solution.
18,500
29
[]
student
yeah...
18,500
30
[]
volunteer
Great. So I'll let you do that whiteboard
18,500
31
[]
volunteer
So just for clarity, I think you're trying to um
18,500
32
[]
volunteer
re-multipply, but you're trying to factor, so I'll help create like kind of the bare bones. One second.
18,500
33
[]
student
okay.. by the way, can I take notes?
18,500
34
[]
volunteer
Of course, you can take notes, yeah. Like write down anything you want.
18,500
35
[]
student
Thanks!
18,500
36
[]
volunteer
Basically, like, you know
18,500
37
[]
volunteer
try to put these into two different categories like this one will go here.
18,500
38
[]
volunteer
this one will go here
18,500
39
[]
volunteer
if that makes sense
18,500
40
[]
volunteer
OK
18,500
41
[]
volunteer
OK, so
18,500
42
[]
volunteer
yeah, I think, I think we're, we're a bit off here. One second. So we're not trying to multiply. We're trying to trying to factor.
18,500
43
[]
student
okay..
18,500
44
[]
volunteer
So they take away the arrows for one second.
18,500
45
[]
volunteer
Um
18,500
46
[]
volunteer
so let's just deal with the first part. Let's actually ignore kind of the second part. Don't let me create a little division here.
18,500
47
[]
volunteer
Our blue, we'll have our blue line.
18,500
48
[]
student
Can you erase it so i can see everythingclearly
18,500
49
[]
volunteer
It'll be our dividing line for now. Actually I'll even make it simpler. I'll just take out this.
18,500
50
[]
volunteer
part altogether
18,500
51
[]
volunteer
So, yeah, I can erase everything.
18,500
52
[]
student
thanks!
18,500
53
[]
volunteer
So basically, if you're just going to factor this part in green, how would you, how would you factor it?
18,500
54
[]
volunteer
What would you take out
18,500
55
[]
volunteer
Then you can write it on the whiteboard
18,500
56
[]
student
You would take out the 3 and 3, basically the exponents
