So, we have given here the beta that is basis that is question number 9 and the base set beta is equal to and that is we have given here minus 2, 5, 3 and 10.
00:23
So, from here we have to write here our set we need to consider the linear combination that is x1 into minus of 2, 5 plus x2 of 3 and 10 is equal to 0.
00:55
Now, so from here we need to write that is minus 2, 3, 5 and 10 multiply with we need to write here that is x1 and x2.
01:18
So, after simplify this we need to write here that is we need to write this matrix into augmented form so minus 2, 3, 5, 10 augmented with b that is 0, 0.
01:35
So, first we need to apply here the operation the operation is r2 tends to r2 divide by 2 so from here we our matrix become minus 2, 3 and it becomes 2 and it becomes divided by 5, 5 so it become from there that is 1 and 10, 1 and 2, 1 and now we need to apply here the operation that is r1 is r1 plus r2.
02:27
So, from here we need to write that is minus 1 plus 5 and it becomes 1 and so after simplify this we will get that next operation we need to apply here r1 is minus of r1 so it become from there that is 1 minus 5, 1, 2...
