[00:00:00]Exercise 2.1.2.

[00:00:24]Exercise 2.2.

[00:00:28]Exercise 2.2.

[00:00:32]exercise.

[00:01:08]for a x² + b x + c.

[00:01:35]Foreign speech. Foreign speech. Foreign speech.

[00:01:50]already.

[00:02:14]That means for a x² + b x + c.

[00:02:54]Foreign speech. Foreign speech. Foreign speech.

[00:03:07]Foreign speech. Foreign speech. Foreign speech.

[00:04:03]for XUS alpha XUS beta X - Al XUS beta Alpha plus beta. Alus by mean.

[00:05:48]A square.

[00:06:02]Windomost.

[00:06:16]Yes or no?

[00:06:21]A square.

[00:06:32]We Yes or no X square X.

[00:07:12]That means by Fore x² x alus betain Okay.

[00:08:11]Fore XUS beta X + B + C * K * X - Ala K * X - alpha into X Or you can say that dur Stop. Okay.

[00:09:44]Same a x² + b x + c into x.

[00:10:04]This implies a x² + b x + c = k * x² beta x - ala x plus alpha into beta a x² + b x + c= k * x² Beta plus alpha plus alpha into beta x² plus beta a x² + b x + cip k x²us k * k * beta plus k * alpha into beta.

[00:11:22]Yes or no? Yes. Okay.

[00:11:29]for Got respected but corresponding compon X B=us of minus of K * Ala plus beta al Yes or no * betus k into beta= value B / B / Kus Balus B Al beta is equal by Alus B.

[00:13:53]Alus by I think max C* * betal into beta C.

[00:14:50]This implies C / C by A.

[00:15:40]X= A + B.

[00:16:09]X + B * X into X number X² Foremost into X².2 A x + b x² + c X plus beta plus gamma into beta plus beta into gamma plus gamma into alpha Ala plus into next minus minus plus again minus B Okay. Next.

[00:18:47]plus next minus by next exercise 2.2 Main theory main concept.

[00:19:18]Definitely 2.2 x + 7.

[00:19:36]Definitely.

[00:19:47]Okay.

[00:19:57]Foreign speech. Foreign speech.

[00:20:34]Okay.

[00:20:44]+ 7 x + 10.

[00:20:47]Yes or no?

[00:21:01]1 x square b.

[00:21:07]Okay.

[00:21:23]1 into 10. 1 into 10.

[00:21:35]Foreign speech. Foreign speech.

[00:22:03]Foreign speech. Foreign speech. Foreign speech.

[00:22:37]Definitely definely.

[00:23:05]Main concept.

[00:23:20]Definitely definitely One into 10 out 11.

[00:23:57]2 + 5.

[00:24:17]2 x² + into x + X² + 2 X + 5 X 5 X Okay.

[00:25:12]X + X + X + 5 X= -2.

[00:26:11]US.

[00:26:16]Okay.

[00:26:22]X Next.

[00:26:51]Next.

[00:26:56]Wait, what?

[00:27:09]Busous C value 10 B value 7 C value 10 US Busely definitely -ely that means - A - 7.

[00:29:33]Extra extra hook.

[00:29:38]divided by one.

[00:29:42]1 2 ABC 7.

[00:30:30]I don't know.

[00:30:50]- 2 into - yes or no window.

[00:31:19]C by Afinely.

[00:31:38]Simple 10.

[00:32:15]main solution.

[00:32:28]Act number 2.2 Next example. Example.

[00:32:40]Next example.

[00:32:51]for xus.

[00:33:18]A square bul x -<unk> into x + roo<unk> X value minus roo<unk> minus roo<unk> Google for next.

[00:34:46]T plus one. Bus mean by 1.

[00:35:27]Definitely.

[00:35:46]X one. That means for minus root plus a value by So minus 3 by 1us 3us definely cid a x.

[00:37:04]Yes sir.

[00:37:18]Okay. Okay. Next question. Example five.

[00:37:29]Btus 1.

[00:37:38]Next question. B.

[00:37:46]Okay. Next question. A + C + B= A X² square + b x + c.

[00:38:34]One of P into 1 + b into 1 + c. That mean A2.

[00:39:36]A x² + x + a x² + x + a x² 1 + x + Ala yes or no A minus by this implies - 1 by 7 alpha value into alpha= a square = 1 again= Simplification.

[00:41:59]A square= 1 + 1 by roo<unk> roo<unk> 1 by 4 plus 1 plus - 1 by 2 plus 1 by 2.

[00:42:46]A + C + B X² + B US - one of P A into -1² + B into -1 + C of A A plus plus a c= a + c= b a + c= A minus B A plus C Cusal Pusalus US C2 option.

[00:45:00]Next question.

[00:45:03]Okay.

[00:45:14]forchech.

[00:45:52]B C man. A B C or C minore.

[00:46:22]foreign a x² + b x.

[00:46:51]Yes.

[00:46:53]A square plus B.

[00:47:08]Basically minus information.

[00:47:36]for minus forc Fore! Foreign! Foreign!

[00:48:36]That means A B C information about me. Amen.

[00:48:59]for me.

[00:49:13]Same question. Same question.

[00:49:42]Fore B2 basically minus Busus B.

[00:50:10]indigench.

[00:50:58]- 3 by 1us 3 by 1 2% 2 We have a means value.

[00:51:47]value.

[00:52:12]A 1 into x² + b into x + c 2 1 x² + 3x + x² + 3x + 2 x² + 3x Yes, definitely.

[00:53:04]2x² + 6 x + 4.

[00:53:26]A condition based question definitely. forchech.

[00:54:25]for x² - alpha + beta into x plus alpha into beta for XY X into X window.

[00:55:38]Alpha bet.

[00:55:52]K * X² + beta into X plus alpha into beta. A condition for Yes or no?

[00:56:33]Next question.

[00:56:50]- 2 x²us xusify.

[00:57:12]x² + 3x + 2 x + 3x + 2 by pxal That mean solution.

[00:58:22]P of X P of XQ - 5 X² - 11 X - - 11 X minus a B - C 11 or D minus A B - 5 C - 11 or D minus 3 Yeah A whole t B man whole - 5 C man whole - 11 DUS P of T into TQ - 5 into T² - 11 into tus t into t no - 5 into 9us 11 into tus 81us 40 81 1 45 36 81 81us 81 P of = -1 P of -1 = into -1 - 5 into -1² -1 into -1 - 3 into -1 - 5 into 1 1 square - 1 square 1 + 11 - t - t - 5 + 11 - 11 - 8 + 8 p of p of -1 = p of - 1 by T of - 1 by T X - 1 by T into X - 1 by T cube - 5 into -1x T² - 11 into -1x T - T into -1 / 27 - 5 into 1 / 9 + 11 divided by t minus tus 1 by 9 - 5 by 9 - 5 by 9 that's last 11 by t minus Yes.

[01:02:42]LMUS 9 sorry 9 - 6 + 33 - 27 / 9 - 6 - 27 - 20 30 - 33 + 30 divided by 9 that means 0 by 9 0 by 9 P of P of - 1 by T= 9 T - 1 - 1 by T px So window t - one r - 1 by t - 1 - 1 by px of px px It's okay.

[01:04:25]plus beta plus gamma 1 by simplify 2 - 1 by t 2 - 1 by t 6 - 1 5 alpha into beta into gamma sorry into beta plus beta into gamma plus gamma into alpha into beta plus beta into gamma a 1x ta - t - 6 + 1 by t - 18 + 1us - 4 - 4 + 1 by t simplif into beta into gamma t into -1 into -1 by ta plus beta plus gamma plus beta plus beta into gamma alus meaning Ache.

[01:06:55]B minus of - 5 by 3 value B value - 11 - 11 Cus d a minus of minus / a a minus a cusche.

[01:07:53]Exercise 2.2.2.2 question 2.2 Thank you.
