00:54three parenthesis start x minus two whole square is equal to x into parenthesis start x minus two

01:01so let's go to the next step

01:03here we have a question here

01:09three into x minus two whole square is equal to x into parenthesis x minus two

01:14now we will expand the formula

01:17parenthesis on the left hand side

01:20x square minus four x plus four is equal to x square minus two x on right hand side

01:26three x square minus twelve x plus twelve is equal to x square minus two x

01:32two x minus ten x plus twelve is equal to zero

01:37अब देखें three x square में से हम x square minus करेंगे जब इदर ये आएगा तो इसका positive sign negative sign में convert हो जाएगा तो two x square बजेगा

01:48ये minus two x अब इदर आएगा तो plus two x हो जेगा तो minus twelve x plus two x is equal to minus ten x plus ten is equal to zero

01:57x square two common ले आपने minus five x plus six is equal to zero

02:01now we are going to use the quadratic formula

02:03a is equal to one

02:05b is equal to minus five c is equal to six

02:08then

02:09amura is here

02:12minus b plus minus

02:14under

02:15square root

02:16b square minus four

02:17a c divided by two a

02:18b मार पास करें minus five

02:21minus five into minus five

02:22plus five plus minus five

02:24minus five करें plus twenty-five

02:26minus four

02:27into a one

02:29into c six

02:30twenty-four

02:31divided by two into

02:32one

02:33two a

02:33five plus one

02:35plus minus

02:36square root one

02:38five plus one

02:40five plus minus one divided by two

02:44so अब हम इसको

02:45plus और minus साथ साथ करते हैं

02:48five minus one divided by two

02:50five plus one divided by two

02:51six by two

02:52six by two

02:53sorry

02:54four by two

02:55six by two

02:56two and three

02:58the solution set is two by three

03:00तो आप इसको verify भी कर सेटे हैं

03:02यहां किसी पर question में put करेंगे हैं

03:05तो आप देखे हैं कि हम यहां two put करते हैं

03:06तो two minus two zero

03:07everything become zero

03:09two minus two zero

03:11everything become zero

03:12तो उमित करते हूं आपको यह

03:15पार्ट

03:16one काया

03:17जो पार्ट a है

03:19उसका यह सुलस्षन समझ में आया होगा

03:22तो आप comment section में पूछ सकते हैं

03:24अब हम question number two की तरफ जाते हैं

03:29so that

03:38w raised to power 40 plus

03:44omega raised to power 40 plus omega raised to power 50 plus 1 is equal to zero

03:49चला हम इसका सुलस्षन की तरफ जाते है

03:52question number one का part B show that omega 40 plus omega 50 plus 1 is equal to zero

04:04here is the solution

04:06we know that omega cube is equal to one omega into omega square is equal to one

04:11क्या किया है स्टप में हमने omega cube को split कर ते है

04:17two parts में और देन दें करके base यह हो तो उनकी powers को add कर लेते है

04:21similarly, omega scale is equal to one by omega or omega is equal to one by omega scale

04:27further we know that one plus omega scale is equal to minus w or w omega plus omega scale is equal to minus one

04:35so here is the real question given in the question paper

04:40so omega raised to power 4 raised to power 10 plus omega raised to power 5 raised to power 10 plus 1 is equal to zero

04:49omega 4 go split किया है omega 3 into omega raised to power 10 plus

04:55omega 3 into omega 2 raised to power 10 plus 1 is equal to zero

04:59then w3 omega 3 is equal to 1 we know that so only omega left here omega raised to power 10 plus

05:09again omega cube is equal to 1 omega raised to power 10 plus 1 is equal to zero

05:15we know again we are going to split omega 5 raised to power 2 and omega scale is equal to 1 by omega raised to power 10 plus 1 is equal to zero

05:27again we are going to split omega 3 into omega 5 here and then we split omega 5 into again omega cube into omega square

05:45whole square plus 1 is equal to zero so omega cube is equal to 1 omega square raised to power square plus 1 by omega square because omega cube is equal to 1

05:49omega square raised to power 2 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus 1 plus

06:19omega plus k plus 1 is equal to 0 omega plus minus k is equal to minus 1 so we put this

06:25minus 1 plus 1 is equal to 0 so this is a solution i hope you will like this one
