Find a basis of the row space of the matrix

\"A=\"
\"\\left.\\vphantom{\\begin{array}{c}\\!\\strut\\\\\\!\\strut\\\\\\!\\strut\\\\\\!\\strut\\\\\\end{array}}\ 0 -2 4 -1 \"\\left.\\vphantom{\\begin{array}{c}\\!\\strut\\\\\\!\\strut\\\\\\!\\strut\\\\\\!\\strut\\\\\\end{array}}\
8 -2 -14 2
-4 3 3 0
.

Solution

Step 1: Swapping R2 with R1:

Step 2: Add (1/2 * R1) to R3:

Step 3: Add R2 to R3:

Because we have found pivots in columns 0 and 1.

Therefore, the Column Space is given by the following equation:

A *

+B *

where A and B are any real numbers.
