00:00:02.040 --> 00:00:05.150 A:middle L:90%
Okay, We're going to be solving this expression.
2
00:00:05.540 --> 00:00:08.330 A:middle L:90%
The first thing here to do is to remember first
3
00:00:08.330 --> 00:00:11.449 A:middle L:90%
, that we have to figure out the equations.
4
00:00:11.839 --> 00:00:15.230 A:middle L:90%
Sorry. Expressions, signs. So we see that
5
00:00:15.230 --> 00:00:18.010 A:middle L:90%
there's this attraction sign in the middle that applies to
6
00:00:18.010 --> 00:00:23.350 A:middle L:90%
this entire parentheses. So we're going to multiply it
7
00:00:23.350 --> 00:00:25.390 A:middle L:90%
out. Remember that when you have this kind of
8
00:00:25.390 --> 00:00:28.730 A:middle L:90%
negative here, it's going to multiply out to each
9
00:00:28.739 --> 00:00:32.359 A:middle L:90%
term. It's like multiplying by negative one s o
10
00:00:32.359 --> 00:00:33.640 A:middle L:90%
. We're going to go ahead and do that.
11
00:00:33.640 --> 00:00:36.929 A:middle L:90%
First, you're gonna have to x squared minus for
12
00:00:37.020 --> 00:00:40.759 A:middle L:90%
and this negative right here. This negative sign it's
13
00:00:40.759 --> 00:00:45.179 A:middle L:90%
going to turn into a positive sign After we multiply
14
00:00:45.179 --> 00:00:47.130 A:middle L:90%
all of this out And what I mean by that
15
00:00:47.130 --> 00:00:49.289 A:middle L:90%
I'll show you in a second, eh? So
16
00:00:49.289 --> 00:00:51.560 A:middle L:90%
we're going to first take this negative and multiply it
17
00:00:51.560 --> 00:00:55.320 A:middle L:90%
by a negative negative, multiplied by a negative.
18
00:00:55.329 --> 00:00:58.850 A:middle L:90%
Always gives you a positive. So it's a happy
19
00:00:59.740 --> 00:01:03.560 A:middle L:90%
sleeping person. Sleeping bear. Whatever knowledge you'd like
20
00:01:03.560 --> 00:01:07.219 A:middle L:90%
to use right there. Do you have your two
21
00:01:07.219 --> 00:01:19.870 A:middle L:90%
ex Quinn? And now we're going to multiply this
22
00:01:19.870 --> 00:01:21.829 A:middle L:90%
out. So this three acts were going to leave
23
00:01:21.829 --> 00:01:23.760 A:middle L:90%
this sign empty for a second and I'll tell you
24
00:01:23.760 --> 00:01:26.250 A:middle L:90%
why in a minute. So negative times negative,
25
00:01:26.250 --> 00:01:29.390 A:middle L:90%
like I said before is a positives. And out
26
00:01:29.390 --> 00:01:38.670 A:middle L:90%
this is a positive three x squared can. Now
27
00:01:38.670 --> 00:01:42.049 A:middle L:90%
we multiply this one. So we've done this,
28
00:01:42.379 --> 00:01:47.269 A:middle L:90%
Ramana Months multiplied out Excuse me all the way over
29
00:01:47.269 --> 00:01:51.239 A:middle L:90%
here, and that's going to give you in negative
30
00:01:51.239 --> 00:01:55.069 A:middle L:90%
times a positive. Do you have a negative times
31
00:01:55.069 --> 00:01:57.329 A:middle L:90%
? A positive that's going to give you a negative
32
00:01:57.340 --> 00:02:00.159 A:middle L:90%
because you're half a spy. Sleep and half awake
33
00:02:00.159 --> 00:02:04.489 A:middle L:90%
. No one's happy there time, So that's a
34
00:02:04.489 --> 00:02:10.569 A:middle L:90%
negative to X. All right Now, once again
35
00:02:10.569 --> 00:02:14.629 A:middle L:90%
, we have our negative times a negative. So
36
00:02:14.639 --> 00:02:16.490 A:middle L:90%
all the way over here to our last term,
37
00:02:16.490 --> 00:02:19.840 A:middle L:90%
which is negative. Seven. You're going to end
38
00:02:19.840 --> 00:02:23.000 A:middle L:90%
up with a positive. We have a happy sleeping
39
00:02:23.000 --> 00:02:28.080 A:middle L:90%
bear. Positive seven. Now, I left the
40
00:02:28.080 --> 00:02:30.080 A:middle L:90%
parentheses on here so you can see that we did
41
00:02:30.080 --> 00:02:32.740 A:middle L:90%
the entire terms all every single term within the parentheses
42
00:02:32.740 --> 00:02:37.849 A:middle L:90%
. Excuse me, but it's actually not necessary anymore
43
00:02:37.849 --> 00:02:40.370 A:middle L:90%
because the parentheses were only there due to the negative
44
00:02:40.370 --> 00:02:45.129 A:middle L:90%
sign. Now this parentheses could be taken away,
45
00:02:49.419 --> 00:02:53.930 A:middle L:90%
and you can have a positive a sign from the
46
00:02:53.939 --> 00:02:55.849 A:middle L:90%
three x cred Actors in addition, Sign. So
47
00:02:55.849 --> 00:02:59.719 A:middle L:90%
now let's just go ahead and combine like terms you
48
00:02:59.719 --> 00:03:02.509 A:middle L:90%
haven't X squared here and an X squared here and
49
00:03:02.509 --> 00:03:07.800 A:middle L:90%
that becomes a five x squared because three plus two
50
00:03:07.800 --> 00:03:09.889 A:middle L:90%
is five. The reason why we can combine is
51
00:03:09.889 --> 00:03:14.099 A:middle L:90%
because they're like terms they have, like exponents.
52
00:03:14.520 --> 00:03:19.280 A:middle L:90%
Next, the next lowest exponents is X to the
53
00:03:19.280 --> 00:03:22.520 A:middle L:90%
power of one or negative two. X is our
54
00:03:22.520 --> 00:03:30.889 A:middle L:90%
term, and our last one is negative for and
55
00:03:30.889 --> 00:03:34.659 A:middle L:90%
positive. Seven. Negative four plus positive seven gives
56
00:03:34.659 --> 00:03:38.189 A:middle L:90%
you a total of positive three. Which means that
57
00:03:38.189 --> 00:03:43.009 A:middle L:90%
your answer is going to be five x squared minus
58
00:03:43.009 --> 00:03:47.680 A:middle L:90%
two X plus three for an answer and no.
