Got it
17,208
13
[]
volunteer
Then add the 1 and -6
17,208
14
[]
volunteer
Then repeat the process
17,208
15
[]
volunteer
So now we would do -6 x -5
17,208
16
[]
volunteer
Now the results are at the bottom
17,208
17

volunteer
The last term is always the remainder
17,208
18
[]
student
oh okioki
17,208
19
[]
volunteer
And the other terms are applied to increasing powers of x starting from 0
17,208
20
[]
student
so whts hte fa
17,208
21
[]
volunteer
So for -5 it would be -5x^0 which is just -5
17,208
22
[]
volunteer
Then 1x^1 which is x
17,208
23
[]
volunteer
If there's any remainder, you would write that over the existent divisor
17,208
24
[]
volunteer
Since the remainder is 0 it makes no difference
17,208
25
[]
student
Hmm
17,208
26
[]
student
then the next numberr??
17,208
27
[]
volunteer
Which number?
17,208
28
[]
student
x+2 so i can do 2 --2
17,208
29
[]
volunteer
Ok
17,208
30
[]
volunteer
Do you understand this?
17,208
31
[]
student
yup
17,208
32
[]
volunteer
That's great!
17,208
33
[]
volunteer
Do you still want my help for the other questions?
17,208
34
[]
student
what why is 2 -2 when in x+2 is x+2
17,208
35
[]
student
you change signs?
17,208
36
[]
volunteer
For the denominator (i.e. divisor), you're supposed to solve for the root of x
17,208
37
[]
volunteer
So in this case you would do x+2=0, which would give x=-2
17,208
38
[]
student
ohhh I see
17,208
39
[]
student
wait
17,208
40
[]
student
plz check
17,208
41

student
4-3-12-32
17,208
42
[]
student
if you have any corrections feel free to correct in the thing i did
17,208
43
[]
volunteer
Ok
17,208
44
[]
volunteer
What's this?
17,208
45
[]
student
4 as we bring the first one down(?)
17,208
46
[]
volunteer
Yeah, that's correct, it was just a bit hard to read
17,208
47
[]
student
then abt abt -3-12-32
17,208
48
[]
volunteer
The final answer is wrong
17,208
49
[]
volunteer
Wait I'll write in red
17,208
50
[]
student
Understood
17,208
51
[]
student
whast the fa
17,208
52
[]
volunteer
Perfect
17,208
53
[]
student
plz check
17,208
54
[]
volunteer
Sure
17,208
55
[]
student
The solution is below the worksheet
17,208
56
[]
volunteer
Ok
17,208
57
[]
student
can you check
17,208
58
[]
volunteer
Yeah
17,208
59
[]
volunteer
-3x-2=6
17,208
60
[]
student
okay next
17,208
61
[]
student
oki please checkk
17,208
62
[]
volunteer
You should put the values in descending order of powers of x
17,208
63
[]
volunteer
So 3 should be first not lasr
17,208
64
[]
student
oh
17,208
65
[]
student
plz check
17,208
66
[]
student
can you write it with the variables?
17,208
67
[]
volunteer
Yes that's correct
17,208
68
[]
student
can you check
17,208
69
[]
student
can you do (2x^3 - 9x^2 + 4x + 12) / (2x-3)
17,208
70
[]
student
also check for (2x^3 - 9x^2 + 4x + 12) / (2x-3) i did the fa
17,208
71
[]
volunteer
Yes it's correct
17,208
72
[]
volunteer
9+2=1
17,208
73
[]
volunteer
9+2=11
17,208
74
[]
student
also can you do (2x^3 - 9x^2 + 4x + 12) / (2x-3) plz?
17,208
75
[]
volunteer
It's the same concept, equate the denominator to 0, solve for x, then apply synthetic division
17,208
76
[]
student
i dont get it plz helpp
17,208
77
[]
volunteer
For the divisor, you need to solve for x in 2x-3=0
17,208
78
[]
volunteer
And then the rest of the steps are the same
17,208
79
[]
student
huh i dont get it tot
17,208
80
[]
student
can you solve (2x^3 - 9x^2 + 4x + 12) / (2x-3) plz
17,208
81
[]
student
huh
17,208
82
[]
volunteer
It's the same steps, you're just multiplying and adding fractions instead of whole numbers
17,208
83
[]
student
plz can you do itt??
17,208
84
[]
student
dont get it??
17,208
85
[]
volunteer
I've written it in red
17,208
86
[]
volunteer
I'll explain it to you step by step
17,208
87
[]
volunteer
First for the divisor, we solve for x in 2x-3=0, which gives x=3/2
17,208
88
[]
student
lets do it together
17,208
89
[]
volunteer
I'll solve it in the gray box
17,208
90
[]
student
Okay
17,208
91
[]
volunteer
Do you understand so far?
17,208
92
[]
student
yup
17,208
93
[]
volunteer
3/2 x 3 = 9/2
17,208
94
[]
volunteer
-9+9/2=-9/2
17,208
95
[]
volunteer
3/2 x -9/2 = -27/4
17,208
96
[]
student
oh okoki
17,208
97
[]
volunteer
-4+(-27/4)=-43/4
17,208
98
[]
student
oh okiki
17,208
99
[]
volunteer
3/2 x -43/4 = -129/8
17,208
100
[]
volunteer
12+(-129/8)=-33/8
17,208
101
[]
volunteer
That's it
17,208
102
[]
student
oh okioki
17,208
103
[]
student
is it correct??
17,208
104
[]
volunteer
The denominator should be 2x-3
17,208
105
[]
volunteer
For the last term
17,208
106
[]
student
huh
17,208
107
[]
volunteer
We always use the denominator of the original question
17,208
108
[]
student
thank youu
17,208
109
[]
volunteer
No problem!
