OK.
16,143
228
[]
volunteer
OK
16,143
229
[]
student
So how would I do it? Like,
16,143
230
[]
student
would I
16,143
231
[]
volunteer
Um
16,143
232
[]
student
start
16,143
233
[]
volunteer
I'm not sure what, what is
16,143
234
[]
volunteer
so what is a teacher
16,143
235
[]
volunteer
what is this giant F mean
16,143
236
[]
volunteer
That's a different function
16,143
237
[]
student
oh
16,143
238
[]
volunteer
Is that included too
16,143
239
[]
student
No, oh my, I think I add, oops.
16,143
240
[]
student
It's a lowercase f. I think my uh capitalize.
16,143
241
[]
volunteer
Oh, OK. OK
16,143
242
[]
student
Hm
16,143
243
[]
volunteer
I, cause that, I thought that was a different one. Does that make sense?
16,143
244
[]
volunteer
Um.
16,143
245
[]
volunteer
so
16,143
246
[]
volunteer
do you know how to add and subtract the
16,143
247
[]
volunteer
different variables
16,143
248
[]
volunteer
That's an important thing to understand first.
16,143
249
[]
volunteer
So let's say we have, let's see.
16,143
250
[]
student
I, I'll, I'll see.
16,143
251
[]
volunteer
Mhm.
16,143
252
[]
volunteer
Let's say we have
16,143
253
[]
volunteer
uh, where's my pen.
16,143
254
[]
volunteer
X
16,143
255
[]
volunteer
uh, squared.
16,143
256
[]
volunteer
plus
16,143
257
[]
volunteer
let's see
16,143
258
[]
volunteer
X cubed
16,143
259
[]
volunteer
5 XQ plus 3XQ.
16,143
260
[]
student
That'll be 8SQ.
16,143
261
[]
volunteer
Mhm.
16,143
262
[]
volunteer
Perfect.
16,143
263
[]
volunteer
How about
16,143
264
[]
volunteer
4 X.
16,143
265
[]
student
Mhm
16,143
266
[]
volunteer
+ 4 x 2.
16,143
267
[]
student
probably 8 x 2.
16,143
268
[]
volunteer
Yeah.
16,143
269
[]
student
because the bear was listening
16,143
270
[]
volunteer
So the idea is
16,143
271
[]
volunteer
if the exponent is the same.
16,143
272
[]
volunteer
you can just add the coefficient. So,
16,143
273
[]
student
What if he chooses me
16,143
274
[]
volunteer
or add or subtract
16,143
275
[]
volunteer
Yeah
16,143
276
[]
student
What if it's different
16,143
277
[]
volunteer
So
16,143
278
[]
volunteer
let's say we have 5
16,143
279
[]
volunteer
X cubed
16,143
280
[]
volunteer
plus 4 x 2.
16,143
281
[]
volunteer
What would that be
16,143
282
[]
student
Mm
16,143
283
[]
volunteer
Or what's your best guess?
16,143
284
[]
student
A um
16,143
285
[]
student
um, to be honest, I'll put 8 XQ 1 A X
16,143
286
[]
student
squared together
16,143
287
[]
student
variables
16,143
288
[]
volunteer
So, the, the thing is it only works when they're the same
16,143
289
[]
volunteer
It's like
16,143
290
[]
student
Uh
16,143
291
[]
volunteer
see
16,143
292
[]
student
so that means do I add the verbals? That means 3 + 2.
16,143
293
[]
student
5.
16,143
294
[]
volunteer
uh no
16,143
295
[]
volunteer
So
16,143
296
[]
volunteer
it would be different
16,143
297
[]
volunteer
So we're just talking about addition and subtraction. It's just, it's totally different if we're talking about multiplication or division.
16,143
298
[]
volunteer
But that's a different thing entirely. In that case,
16,143
299
[]
volunteer
you kind of group, group it together.
16,143
300
[]
volunteer
and then you could add
16,143
301
[]
volunteer
But
16,143
302
[]
volunteer
when we're, we're, we're, we're talking about now.
16,143
303
[]
volunteer
which is just adding and subtracting
16,143
304
[]
volunteer
You're just trying to find the similar exponents.
16,143
305
[]
volunteer
And if they're not the same, so I said this one was
16,143
306
[]
volunteer
uh addition
16,143
307
[]
volunteer
You can't really simplify it any further.
16,143
308
[]
volunteer
Um
16,143
309
[]
student
So that'll be
16,143
310
[]
volunteer
So
16,143
311
[]
volunteer
this is kind of a trick question. It would be 5 X cube
16,143
312
[]
volunteer
plus 4 x 2.
16,143
313
[]
volunteer
Now if I had, for example,
16,143
314
[]
volunteer
5 X cube
16,143
315
[]
volunteer
+ 4 x 2.
16,143
316
[]
volunteer
plus 4 x 2.
16,143
317
[]
student
oh.
16,143
318
[]
student
easy, and I'll be
16,143
319
[]
student
uh
16,143
320
[]
student
5
16,143
321
[]
student
X
16,143
322
[]
student
cube
16,143
323
[]
student
plus
16,143
324
[]
student
8
16,143
325
[]
student
X squared
16,143
326
[]
volunteer
Yeah, exactly
16,143
327
