So, here we are given the function f of x1, x2 is equals to the x1 minus 2 that whole square plus the x2 plus 1 that whole square.
00:16
So, we have to minimize this function and subject it to 2x1 plus 3x2 minus 4 is equals to 0 in a of x1 and x2.
00:28
So, let us put this inside so that we can minimize this 2.
00:33
So, this can be equals to the 4 minus of 3 times of x2 over 2 minus of 2 that whole square plus the x2 will be as it is plus the 1 that whole square.
00:49
So, basically we are finding for f of x2.
00:52
So, this can be equals to 9 of x2 that whole square divided by 2 to the 4, 3, 3 is a 9, 2 to the 4, then plus of this will become x2 plus 1 that whole square.
01:06
So, let us differentiate this with respect to the x2.
01:10
So, we get 9 by 2 is a common derivative of this term will going to be 2 will be comes in forward and that is why it is becoming 2 here and it will remain only x2 plus the 2 times of x2 plus 1 this would be equals to 0.
01:28
So, simplifying this terms we get 13 times of x2 is equals to minus of 4 this will gives us the value of x2 equals to minus of 4 by 13 and hence we get x1 is equals to 12 by 13 plus 4 divided by the 2...
