00:00Question number 5
00:03A has given a square
00:05and a plus 1
00:08Second row
00:09B
00:09B square
00:101 plus BQ
00:11Third row
00:12C
00:12C square
00:131 plus CQ
00:14A
00:15So
00:18We are saying
00:19that
00:20if this is 0
00:22and if it is equal to 1
00:24plus A
00:25B
00:26C
00:26and if it is equal to 0
00:27Let's say a short track
00:29I will tell you
00:29First column
00:32Second column
00:33Just one element
00:34In the third column
00:36we have two elements
00:361 is
00:381 is
00:391 is
00:39BQ
00:401 is
00:40CQ
00:41So whenever we can do it
00:43we can break this
00:44What does it happen?
00:46So
00:47We can make two places
00:48Mattress
00:51First column
00:52Hazard Ways
00:52and the second
00:53Break it
00:54Here
00:541-1
00:55Lick to
00:55Here
00:56AQ
00:56BQ
00:57CQ
00:57Lick to
00:58Now
00:59Why do I have this
01:00Q&A
01:01Why do I have this
01:02I am very complicated
01:02Now we are trying to take A common from R1
01:06B from R2
01:08C from R3
01:09Now
01:11Which one is
01:12This one is
01:13This one is
01:14This one is
01:17A common
01:27Quire
01:28I am very complicated
01:30Why did I do this
01:30I am here?
01:31I have to solve this
01:31I am here
01:33I am here
01:35What is happening here?
01:36What is happening here?
01:36Common
01:36But A-B-C
01:58and this is which column three
02:02and what I will do, I will change the number of columns
02:07okay, this is the question, because we want to take the same way
02:11here, see 1-1 is here and here is this one-1
02:14so I have to take it here or this ABC, I have to take it here
02:18but this is not the problem, because here is the third column ABC
02:22and here is the second column
02:23and when we are interchange, we are minus 12, now I will do a little more
02:28I have to take this, so now I will interchange the C2 and C3 again
02:34who will interchange the C2 and C3
02:40this is what I have done
02:47the result of this, these two are the same mattress
02:50the same, so see, this is the whole mattress, I will do a common one here
02:54and here is the ABC, okay, this thing was already equal to 0, okay
03:00we are going to improve, this thing was already equal to 1 plus A, B, C, B, 0
03:06and now this is what I have done
03:07this is what I have done
03:08and we are just flying toë³´
