Construct a 3 × 3 nonzero matrix A such that the vector [ 1 − 2 1 ] is a solution of A x = 0 .
Construct a 3 × 3 nonzero matrix A such that the vector [ 1 − 2 1 ] is a solution of A x = 0 .
Solution Summary: The author explains how to construct a 3times 3 matrix A, such that the sum of first and third columns is twice that of second columns.
Construct a 3 × 3 nonzero matrix A such that the vector
[

is a solution of Ax = 0.
Quantities that have magnitude and direction but not position. Some examples of vectors are velocity, displacement, acceleration, and force. They are sometimes called Euclidean or spatial vectors.
Solve the linear system of equations attached using Gaussian elimination (not Gauss-Jordan) and back subsitution.
Remember that:
A matrix is in row echelon form if
Any row that consists only of zeros is at the bottom of the matrix.
The first non-zero entry in each other row is 1. This entry is called aleading 1.
The leading 1 of each row, after the first row, lies to the right of the leading 1 of the previous row.

Please help I'm a working mom trying to help my son last minute (6th grader)! Need help with the blank ones and check the ones he got with full calculation so we can use it to study! Especially the mixed number fractions cause I'm rusty. Thanks in advance!
