SUMMARY

The dimension of the solution space for the equation Ax=0, where A is a 2x3 matrix defined as A = [[1, 2, 5], [-1, 3, 1]], is determined to be 1. This conclusion is reached by applying the formula for the dimension of the solution space, which is calculated by subtracting the rank of matrix A from the number of columns (n). Given that the rank of A is 2 and n is 3, the calculation is 3 - 2 = 1, confirming the dimension of the solution space is indeed 1.

Find the dimensions of the soultion space of Ax=0,
where A=
1 2 5
–1 3 1
(A is a 2x3 matrix).


To find the dimension you have to subtract n from rank(A)
//n being the number of columns

3-2=1
The dimension of the solution space is 1. is this correct?
