00:00:00.000 --> 00:00:04.000
For two, then you guys brought food.
2
00:00:04.000 --> 00:00:07.000
Like, this will be my ham, right?
3
00:00:07.000 --> 00:00:12.000
Come Tuesday and I'll fly some pizza for you, miss my logo.
4
00:00:12.000 --> 00:00:14.000
I mean, not good.
5
00:00:14.000 --> 00:00:16.000
We can share it.
6
00:00:16.000 --> 00:00:20.000
Alright, so I need to go and find out I'm doing standard form, right?
7
00:00:20.000 --> 00:00:21.000
Good.
8
00:00:21.000 --> 00:00:24.000
And the remember standard form is a couple things that have to happen.
9
00:00:24.000 --> 00:00:26.000
One thing is we can't have a negative A.
10
00:00:26.000 --> 00:00:30.000
The coefficient of our x-bf variable cannot be negative.
11
00:00:30.000 --> 00:00:38.000
And also, the common factor between our A, B and C have to be, you know, one or the least common factor has to be the least one.
12
00:00:38.000 --> 00:00:41.000
You can't have fraction as your exponents.
13
00:00:41.000 --> 00:00:43.000
So what we need to do is we need to get rid of these fractions.
14
00:00:43.000 --> 00:00:48.000
And when I have fractions that, you know, I have different denominators, I need to find the least common denominator.
15
00:00:48.000 --> 00:00:52.000
So I look at four and five and I say, what is the smallest number that they both go into?
16
00:00:52.000 --> 00:00:54.000
And that is 20.
17
00:00:54.000 --> 00:01:00.000
So now that I have 21, because I'm going to multiply each one of these terms, each one of these terms all done by 20.
18
00:01:00.000 --> 00:01:02.000
Actually, before I do that, let's get them over to the side.
19
00:01:02.000 --> 00:01:05.000
Let's get the x to the y to the same side.
20
00:01:05.000 --> 00:01:14.000
So in negative three-fourths, x, I need to subtract two-fis y on both sides.
21
00:01:14.000 --> 00:01:21.000
So minus two-fis y equals the negative one.
22
00:01:21.000 --> 00:01:27.000
Now what we need to do is I'm going to multiply everything by 20.
23
00:01:27.000 --> 00:01:41.000
So what I'm going to do is I'm going to multiply 20 times a negative three-fourths x.
24
00:01:41.000 --> 00:01:54.000
And then minus 20 again times two-fis y equals negative one.
25
00:01:54.000 --> 00:01:58.000
Now you could multiply by negative 20 if you want to get rid of that negative sign,
26
00:01:58.000 --> 00:02:01.000
but I'm not really concerned by right now, I'll do that right at the end.
27
00:02:01.000 --> 00:02:03.000
But that would be kind of a helpful tip to do.
28
00:02:03.000 --> 00:02:05.000
So here are a couple ways you could do this.
29
00:02:05.000 --> 00:02:13.000
You could divide 20 divided by four, which would be five, and then multiply that by three to get 60, or to get 15, I'm sorry.
30
00:02:13.000 --> 00:02:20.000
Or you could multiply 20 times three to give you 60, divide by four, and either way you're going to get 15.
31
00:02:20.000 --> 00:02:24.000
But since there's no negative sign there, it's going to be a negative 15.
32
00:02:24.000 --> 00:02:43.000
So again, we don't have any fractions.
33
00:02:43.000 --> 00:02:57.000
Besides fractions, we also cannot have a negative a if I need to divide by negative one by everything.
34
00:02:57.000 --> 00:03:24.000
So let's say self-standard form when you have fractional exponents, or fractional coefficients.
