00:00Yes, we are going to do the lesson number 4, exercise 1.1, class 1st year, question number 4, find the multiplications, multiplicative notes of each of the following, okay?
00:25multiple
00:31a
00:33a
00:36a
00:38a
00:39a
00:44a
00:45a
00:46a
00:47a
00:49a
00:50a
00:51a
00:52a
00:53So what we have to do is a square minus 4 and a square is a square and a square is a square and a square is a square minus 4 square plus 7 square
01:07Okay this is minus 4 constituent plus seven seven put to 49
01:16Okay
01:18Uh I like minus 4
01:22Just for quite 49 and this is 16 65
01:28Okay
01:30and I will add
01:34B is equal to 7, which is minus seven, then the square is minus four plus seven.
01:43So this is minus seven to 16 plus 49, okay?
01:49So this is minus seven to 64, so this is minus four, turning left one.
01:56And the negative side, we have to look at the other side of the square root of the square root.
02:15a square and a square
02:17here a square and a square
02:23a square
02:25another square
02:27a square
02:291-b
02:31a square
02:332 with a square
02:35plus 5
02:375
02:39You can put in the square
02:41OK
02:43so I will do this
02:45A square plus B square
02:49and minus B
02:51and A square plus B square
02:55ok
02:57so B is minus
02:59so this minus
03:01A square
03:03plus minus 5
03:05square
03:07square
03:09yes
03:11I
03:13do
03:27is
03:29is
03:31can
03:33get
03:35a
03:37here
03:41then
