For Equation like 12X1-lambda Use Equation option select 2 option 3 x and =dn then put the value carefully like x1 =12 , x2 = not given then 0 , x3 = lambda = -1 and dn=0 sme to all equation check second equation it has x2 directly no x1 so x1 is 0
So People who didn't understood the [12x1-lambda] part let me explain you. Note : I am using casio 991 calculator. Step 1 : press MODE Step 2 : press 5 (where Equation is written) Step 3 : press option no.2 (anX+bnY+cnZ=dn) Step 4 : Now add values of X1,X2,X3 (Eg. 12x1-lambda=0 will written as a:12 b:0(since x2 value is not mentioned) c: -1(lambda value) d: 0 Step 5 : Fill the value as step 4 Step 6 : after fill all row and column press enter and your answer is there.🎉🎉

You get 12x1-lamba =0 10x2-5lambda=0 And x1+5x2=7 Lambda=12x1 Lambda =2x2 So lambda=12x1=2x2 So x2=6x1 Can be written as 6x1-x2=0 Now the third equation which was there i.e x1+5x-7=0 Becomes x1+5x=7 6x1-x2=0 Solve simultaneously on calci and profit

Kumbojkar is a good book
Thank you for your great lecture
Can we solve these equations in calculator fx-991MS ?
how to solve lambda func on the casio 991EX ??
Sir how you get these answer 9:37 plz reply
You get 12x1-lamba =0
10x2-5lambda=0
And x1+5x2=7
Lambda=12x1
Lambda =2x2
So lambda=12x1=2x2
So x2=6x1
Can be written as 6x1-x2=0
Now the third equation which was there i.e x1+5x-7=0
Becomes x1+5x=7
6x1-x2=0
Solve simultaneously on calci and profit

Are you sure sir isme x1 x2 and lemda k values shi aarhe h ?
Sir it is

Nice try but don't try again 😞☠️
Bhai tuze chodke sbko acche se smja hai Ok
Sir, delta is positive then minima and delta is negative then maxima.
How do you know???
sir did it right
delta is negative so z is minimum
Ye 991 nh h 961 hai sir ....
I understood all bcz I did try it somewhere else .... U just don't clarify well.... U need to improve
Sir how to solve this
Using Lagrange's multipliers, solve the following N.L.P.P.
1. Optimise z = 4x1 + 6x2-2x12-2X1X2-2x22
