exactly
13,553
95
[]
student
uh
13,553
96
[]
student
oh, so then that would just be 2 and 18, no?
13,553
97
[]
student
Yeah.
13,553
98
[]
student
Right. Actually, no
13,553
99
[]
volunteer
No, so 43 is 12.
13,553
100
[]
volunteer
Uh, hold on, something's off here.
13,553
101
[]
student
Uh oh
13,553
102
[]
student
Cause there's like two X values though, so.
13,553
103
[]
student
I mean.
13,553
104
[]
student
like there's no way to just find like
13,553
105
[]
student
one value of X, I don't think.
13,553
106
[]
student
Yeah, yeah
13,553
107
[]
volunteer
No, there are two values that actually you need to find, but I am trying to figure out the best way to do this. It's like 12, 3:36.
13,553
108
[]
volunteer
36, uh
13,553
109
[]
volunteer
is 20. When X?
13,553
110
[]
volunteer
Um
13,553
111
[]
student
It's like
13,553
112
[]
student
hm
13,553
113
[]
volunteer
hold on, let, OK, before we jump into this, let me maybe, do you know the basic way of doing this? So for example,
13,553
114
[]
volunteer
X + uh
13,553
115
[]
volunteer
3
13,553
116
[]
volunteer
you know this method, right? So 3 to 6. So if I say X
13,553
117
[]
volunteer
right
13,553
118
[]
student
were you writing that?
13,553
119
[]
volunteer
plus 6, you see this?
13,553
120
[]
student
Uh, oh yeah, no I see it's OK.
13,553
121
[]
student
Um
13,553
122
[]
student
not really.
13,553
123
[]
volunteer
So do you know how to solve this? Like, let me just type it properly, yeah. Do you notice all this
13,553
124
[]
student
Uh
13,553
125
[]
volunteer
How to factorize this. So this is all like this, so you do X to the part 2.
13,553
126
[]
volunteer
then you do + 3X minus 2 X.
13,553
127
[]
volunteer
and then
13,553
128
[]
volunteer
the multiplication of
13,553
129
[]
volunteer
+ 3
13,553
130
[]
volunteer
multiplied by -2.
13,553
131
[]
volunteer
Let me put a dot so that it doesn't seem like two multiplications. You see this now?
13,553
132
[]
student
Mhm
13,553
133
[]
volunteer
So what is happening is 3 multi blood by 22 is -6, and 33 x minus 2 x is X.
13,553
134
[]
student
Me what? Wait, hold on. OK, so
13,553
135
[]
student
OK, but then what was the point of that one.
13,553
136
[]
student
Alex goes off
13,553
137
[ { "pii_type": "PERSON", "surrogate": "Alex", "start": 0, "end": 4 } ]
volunteer
Oh, sorry. So what I'm saying is that you break this down, the X in such a way that 3x minus 2 X gives you the X, correct?
13,553
138
[]
student
Mhm
13,553
139
[]
volunteer
We found the factors of 6, such that the addition gives you the coefficient for the X and the multiplication gives you uh the coefficient, the
13,553
140
[]
volunteer
the
13,553
141
[]
volunteer
the last C number basically.
13,553
142
[]
student
Mhm
13,553
143
[]
volunteer
right? So when you do this, you are able to break this into two factors, which is
13,553
144
[]
volunteer
X.
13,553
145
[]
volunteer
multiplied by
13,553
146
[]
student
Oh, so you're doing like the 2 is in common, right?
13,553
147
[]
volunteer
X + 3. Correct, yeah, yeah, you're right.
13,553
148
[]
student
OK.
13,553
149
[]
volunteer
And then you take the -2 out.
13,553
150
[]
volunteer
and then you'll get the X + 3 inside.
13,553
151
[]
volunteer
So then you have two factors, X minus 2 and X + 3. So X is equal to 2 or X is equal to -3. Does that make sense?
13,553
152
[]
student
No, I got a second.
13,553
153
[]
student
uh
13,553
154
[]
student
um, but.
13,553
155
[]
student
um
13,553
156
[]
student
not
13,553
157
[]
volunteer
Did you, did you understand that or, or slow down.
13,553
158
[]
student
no, sorry.
13,553
159
[]
volunteer
OK
13,553
160
[]
student
OK
13,553
161
[]
volunteer
So what is happening here? Um, so because I'm, I'm sharing this because this should will make the other one easier for you. That's why I'm trying to break down here, OK? And then we'll go to that one.
13,553
162
[]
volunteer
Uh
13,553
163
[]
volunteer
so do, should I write the next step then?
13,553
164
[]
student
Um, could you like explain
13,553
165
[]
volunteer
Are, are you on the same page to? I'm sorry, go ahead.
13,553
166
[]
student
could you explain like the third line, like
13,553
167
[]
student
pretty much
13,553
168
[]
volunteer
The third line? OK, sure, yeah, the third line, right? So what we're doing is
13,553
169
[]
volunteer
let me add a new line, so maybe that's easier than, you know, X is X, correct?
13,553
170
[]
student
Mhm.
13,553
171
[]
volunteer
So what I did here is, if you multiply these two axes, you'll get the X X and X, right?
13,553
172
[]
volunteer
The same thing as that
13,553
173
[]
student
Mhm
13,553
174
[]
volunteer
with me
13,553
175
[]
student
Mm
13,553
176
[]
volunteer
OK
13,553
177
[]
volunteer
And I'm putting dots. That doesn't mean it's decimal, it's just multiplication.
13,553
178
[]
student
Yeah
13,553
179
[]
volunteer
OK. So this is X and if you multiply this 3 with that X, you get 3 X, correct?
13,553
180
[]
student
Uh, yeah, but like
13,553
181
[]
student
aren't you doing X basically times
13,553
182
[]
student
X cause where does the other X go?
13,553
183
[]
volunteer
Which one, sorry? Are you, are you pointing to this?
13,553
184
[]
student
Like
13,553
185
[]
student
is there like a pointer on this, like you can see.
13,553
186
[]
volunteer
Yeah, yeah, I can see, I can see your name on the pointer.
13,553
187
[]
student
OK, OK. So, I know like this is X times X.
13,553
188
[]
student
but I don't know like how this is
13,553
189
[]
student
broken up. Like I know like this, basically.
13,553
190
[]
student
these two
13,553
191
[]
student
convert into
13,553
192
[]
volunteer
Oh, this means 3 daughters. Do you know that?
13,553
193
[]
student
Yeah, I know, I don't means that 3 times X, but
13,553
194
[]
