[00:00:21]Okay, mother.

[00:00:52]Namaskar.

[00:00:55]Sound to clear.

[00:02:53]So highest power.

[00:03:24]description.

[00:03:27]Okay.

[00:03:31]A x² + b x + c.

[00:03:39]uh lighter problem this.

[00:03:48]Okay.

[00:03:58]A not= a square.

[00:04:17]Okay.

[00:04:20]A not equal zero. Okay. Next.

[00:04:26]PX PX to Y= Y= PX Y.

[00:04:46]Okay.

[00:04:57]Okay.

[00:05:16]A x² + b x + c by a c by ach.

[00:05:37]Okay.

[00:05:47]B A C by A.

[00:05:59]So next next topic.

[00:06:09]Okay.

[00:06:16]Okay.

[00:06:32]8 9 7 8 9 Okay.

[00:06:54]Okay.

[00:07:02]12 x 12.

[00:07:23]12.

[00:07:37]Okay.

[00:07:44]Okay.

[00:07:49]into three.

[00:07:53]Next 8 2 4 2.

[00:08:05]So it means A2.

[00:08:21]Next. A2.

[00:08:37]Okay.

[00:08:41]brackets start brackets. So 3x 3x loading. We go problem.

[00:09:25]Okay.

[00:09:29]So okay.

[00:09:51]Okay.

[00:09:55]for x² - 2x - 8.

[00:10:16]Okay.

[00:10:20]Px.

[00:10:22]Okay.

[00:10:41]Okay.

[00:10:57]Okay. 1 into Okay.

[00:11:38]2.

[00:11:49]Okay.

[00:12:24]Next.

[00:12:29]Okay.

[00:12:37]Okay.

[00:12:40]X²us.

[00:12:46]So - 4us plus 2xus.

[00:13:10]Okay.cess Okay.

[00:13:26]X² mean X into XUS 2 into 2 into X. Okay. Next 2 into X. Next.

[00:13:44]Okay.

[00:13:55]bracket start. So brackets close.

[00:14:17]Sorry.

[00:14:19]Okay. Next.

[00:14:24]Do we Okay.

[00:14:59]So x + 2. Okay.

[00:15:11]Okay.

[00:15:17]Okay.

[00:15:24]PX zod.

[00:15:30]So px.

[00:15:40]So x - 4 = 0 by x + 2 = 0. Okay.

[00:15:52]4 x= 2. Okay.

[00:16:05]dutus 2 4us okay.

[00:16:31]Okay.

[00:16:43]Okay.

[00:16:49]Okay. The punk or the car.

[00:16:57]Okay.

[00:17:12]Okay.

[00:17:14]Good. Next. Next.

[00:17:29]window.

[00:17:43]Window Z.

[00:17:57]US by A window C by A C by A.

[00:18:17]Okay.

[00:18:23]by US.

[00:18:37]Next a x² + b x + c.

[00:19:03]Okay.

[00:19:13]Okay.

[00:19:18]Say - 8. Okay. Minus 8. Okay.

[00:19:40]Okay.

[00:19:52]- 2 - 2 sorry plus alpha plus beta minus b by A minus Bus 1. So answer by a minus okay value so - one by table. Next window A. So C means by one. So okay.

[00:21:55]MCQ. for one, two, three, Okay. Next.

[00:22:42]Okay.

[00:22:44]Next.

[00:22:50]Okay.

[00:22:52]Next. Next question.

[00:23:10]Zonabara say next proh.

[00:23:27]Next 4 S² - 4 S + 1 of S 4 S² - 4 S + 1 Okay, Okay.

[00:24:16]So 2 + 2 + s + 1. Okay. 4 s².

[00:24:30]Okay.

[00:24:32]So 22us.

[00:24:37]Okay. Next one.

[00:24:59]Okay.

[00:25:04]2 into 2 s 2.

[00:25:26]Okay. minus 2 s + one.

[00:25:43]Okay.

[00:26:09]Okay.

[00:26:17]Sus. Okay.

[00:26:26]Okay.

[00:26:31]2 S - 1 = 0. So 2 S = 1 S= 1 by 2.

[00:26:43]2 s - 1 = 0. So 2 s= So s= 1 by 2.

[00:27:12]1 by 2 1 by 2. Okay. So we go. Okay.

[00:27:20]Next. Next. Next.

[00:27:32]Fight number two. Number two.

[00:27:36]One is God. Yes.

[00:27:47]Yes. Yes.

[00:27:55]Good night to sorry Bus Cus So 1 by 2 1 by 2. So 1 by 2 + 1 by 2.

[00:28:35]Okay. So 1 by 2 1 by 2 plus 1 + 1 so 2 by 2 so 1 by four.

[00:29:12]direct. Okay.

[00:29:42]AUS.

[00:29:50]Okay.

[00:30:03]Okay.

[00:30:12]Next.

[00:30:22]So 1x 2 into 1 by 2. So 1x4 into C by A. Okay. C by A. Okay. A2 next number two.

[00:31:13]Okay.

[00:31:21]X 6 - 7 X Ministry.

[00:31:58]Okay.

[00:32:09]6 x² 9 - 2 x - 3 x + 2xus 3x 2x - 3 1. Okay. So, 2x - 3 3x + 1. So, Z 2x - 3 = 0 by 3x + 1 = 0. So 2x - 3. So x = 3x 2 3x = -1.

[00:33:05]Okay.

[00:33:10]Next second.

[00:33:17]Okay.

[00:33:23]I am new subscriber. Good.

[00:33:37]That's a plus.

[00:33:49]Okay.

[00:34:00]Al + beta Ala plus beta + gamma= minus b by plus auss.

[00:34:46]Okay, sir.

[00:34:50]Everybody see that?

[00:35:01]Phone number two. Phone number.

[00:35:08]So P So, P U sorry 4 U² + 8 U already.

[00:35:43]So, We are talking about we are talking about two pu z= a2 part a part okay by u + 2= 0. So= 0 that means okay minus Second.

[00:36:30]Second part.

[00:36:45]Okay. Second part.

[00:36:48]Okay. Thank you.

[00:36:51]Next.

[00:37:01]Okay.

[00:37:16]Okay.

[00:37:28]So pt okay t² minus So a condition a square - b square a + b a minus Three.

[00:38:10]A square t.

[00:38:14]Next.

[00:38:29]Okay.

[00:38:33]15 square.

[00:38:45]Okay.

[00:38:51]PT Z T +<unk> 15= 0 by T - <unk>5= 0. Okay. So t=<unk> 15 by t= roo<unk> 15. So whole minus roo<unk> 15 + roo<unk> 15. Okay, sir.

[00:39:35]School 3.1.

[00:39:48]Okay.

[00:39:56]More 15 days.

[00:40:23]Okay.

[00:40:34]Okay.

[00:40:37]Next.

[00:40:41]Next.

[00:40:47]Next. Okay.

[00:41:02]Okay. Namaskar.

[00:41:07]Okay.

[00:41:14]Yeah.

[00:41:16]Okay. Next.

[00:41:19]Next.

[00:41:23]Okay.

[00:41:33]Okay.

[00:41:51]What about Okay.

[00:42:13]Okay. part. Okay.

[00:42:28]square.

[00:42:39]So zero. Okay. Next C means minus 15. So C= 15.

[00:42:58]Okay.

[00:43:05]15 plus roo<unk> 15. So 0 1 0 by 1 that means 0 by a. Okay. Next window.

[00:43:37]Okay. Sous roo<unk>5 into plus roo<unk>5 into roo<unk> 15us that mean same same okay by Okay.

[00:44:12]Daily Okay.

[00:44:44]Okay. So, okay. Next.

[00:44:50]Next.

[00:44:52]3x² - x - 4. So, 3 into 12 3 into 4 into 6 3 into only 1 - 3.

[00:45:18]So 4 - 3 x - 4 3 x² - 4x + 3x - 4. Okay.

[00:45:42]Okay.

[00:45:44]3x - 4 x + 1. Okay.

[00:45:59]Z 3x - 4 = 0 by x + 1 = 0. So 3x = 4. So x = 4 by 3.

[00:46:13]Okay.

[00:46:23]Good.

[00:46:29]Okay.

[00:46:33]Okay. Next.

[00:46:48]Okay.

[00:46:55]1 into 12. Next 2 into 6 and 3 into 4.

[00:46:59]So 3 + 4 4 + 3.

[00:47:05]Okay. 4 + 3 x + 12. So x² + 4 x + 3 x + 12. So, x + 4 x + 4 x + 3 3.

[00:47:27]So, px = z x + 4 = 0 by x + 3 = 0.

[00:47:41]Okay. So x= x= 3.

[00:47:53]Thank you.

[00:48:06]Okay. Next.

[00:48:10]So, px² - 4x + 3.

[00:48:24]So, 1 3 + 1 x + 3. So, x² - 3 x - x + 3. So x 3x 1 i.

[00:48:46]Okay.

[00:49:04]x - 3 = online next.

[00:49:18]Okay.

[00:49:29]homework.

[00:49:34]Okay.

[00:49:50]So 7 1 into 7. Okay. So 7 - 1 x - 7. So x² - 7 x + 1 x - 7. So x - 7 + 1 x - 7. So x - 7 x + 1. So I take px z x - 7 = 0 by x + 1 = 0 x = 7 x= -1 Okay.

[00:50:56]Okay. for next.

[00:51:00]Okay. Next advanc So next.

[00:51:37]Okay. So 2 into 14. So 1 into 14 into 7. Okay.

[00:51:49]7 - 2= 5. So 7 - 2 x a 2. So 2 x² 7 x + 2 x Okay.

[00:52:11]Already A2 plus A2 Okay.

[00:52:58]Next.

[00:53:08]So, 2x = 7.

[00:53:11]x= x = 7 by 2. So next 12.

[00:53:37]Okay. Number nine.

[00:53:40]Yeah.

[00:53:43]X 12.

[00:54:29]Okay.

[00:54:45]Okay.

[00:55:03]slide.

[00:55:15]detaine.

[00:55:32]Okay.

[00:55:40]10.

[00:55:53]P X K X² - alpha + beta X plus alpha beta Z.

[00:56:10]So, bottom slide.

[00:56:28]key. D say got Okay.

[00:56:57]Okay.

[00:57:15]Alpha plus 1 by 4.

[00:57:22]Say pur alpha beta=us.

[00:57:37]Okay.

[00:57:42]Okay.

[00:57:54]PX = K into X² - alpha + beta X plus alpha beta.

[00:58:09]Okay.

[00:58:12]Okay.

[00:58:19]X 1 by 4 XUS.

[00:58:37]Okay. Clear.

[00:59:49]That's sir.

[01:00:04]No sound.
