Transcribed Image Text:A matrix A and an echelon form of A are shown below. Find a set that spans Nul A.
A =
5 11 67 - 25
7 15 91 - 33
3 850 - 22
1 3 19 - 9
01 7 -5

(Simplify your answer. Use a comma to separate answers as needed.)
Expert Solution
Step 1
Null space: Let A is an matrix. The set of all the vectors x consisting of the solutions of the
equation is called the null space of A.
We have the row reduced echelon form of the matrix A. We have to find the basis of the null
space of A.
