00:00:00;00 ---> 00:00:03;06
Leave X squared and divide by 4

2
00:00:04;04 --> 00:00:07;10
X squared has to do with something, yeah

3
00:00:07;10 --> 00:00:08;12
There's two X's

4
00:00:08;12 --> 00:00:19;08
There's definitely not an X squared here, an and yet when it does whatever it does,
it results in X squared, sure. So, maybe that's a hint. Sabrina?

5
00:00:19;09 --> 00:00:23;06
The 4 and 6 are added and multiplied.

6
00:00:24;00 --> 00:00:32;02
Ok, that's actually a really good observation, that the 4 and the 6 are added to make
this, and multiplied to make that.

7
00:00:32;08 --> 00:00:38;03
Ok, that's a really good observation. Tell me more. Matt?

8
00:00:38;04 --> 00:00:41;13
There's two X's. X squared plus X squared.

9
00:00:42;03 --> 00:00:51;11
Ok, so you actually said something that hasn't been, well, Sabrina mentioned it
actually. But how do these two X's make X squared? Matt, you said...

10
00:00:51;13 --> 00:00:53;01
X times X

11
00:00:53;01 --> 00:00:56;08
X times X. Where'd you get the times from?

12
00:01:00;13 --> 00:01:02;02
Samantha?

13
00:01:02;03 --> 00:01:05;06
The whole two factors that we want thing.

14
00:01:05;06 --> 00:01:12;05
Yeah. These two factors are getting multiplied. What's the operation in between them? Well, there's nothing written there, so...

15
00:01:012;06 --> 01:13;06
Multiplication

16
01:13;06 --> 00:01:19;08
Multiplication. If they were being added, I'd have to show a plus sign. If they were being subtracted, I would have to show a subtraction sign.

17
00:01:19;10 --> 00:01:26;09
But if they're being multiplied, just like you guys have seen in the past, if I write 3X, what do I mean?

18
00:01:26;11 --:> 00:01:27;05
3 times X

19
00:01:27;06 --> 00:01:35;06
3 times X. So, if I write X plus 4 next to the parentheses X plus 6. What operation is in between them?

20
00:01:36;07 --> 00:01:37;05
Multiplication

21
00:01:37;05 --> 00:01:45;07
Multiplication. The graphing calculator multiplies it. That's the operation in between
those- it multiplies it. So, the question is:

22
00:01:47;03 --> 00:01:50;07
how do you multiply these two quantities?

23
00:01:52;07 --> 00:01:59;01
How do you multiply those two quantities? I'll give you a hint, it has to do with a
property you learned in first semester.

24
00:02:03;14 --> 00:02:05;03
Danielle?

25
00:02:05;04 --> 00:02:06;06
Distributive

26
00:02:06;06 --> 00:02:07;14
Distributive property.
