Find the basis and dimension of Null A where $A = \begin{bmatrix} 1 & 2 & 3 & 4 \\ 2 & 4 & 7 & 8 \end{bmatrix}$ [5]

Find the basis and dimension of Null A where $A = \begin{bmatrix} 1 & 2 & 3 & 4 \ 2 & 4 & 7 & 8 \end{bmatrix}$ [5]

$A = \begin{bmatrix} 1 & 2 & 3 & 4 \\ 2 & 4 & 7 & 8 \end{bmatrix}$ Matrix has 2 rows, 4 columns ( $n = 4$ variables). We solve $A\mathbf{x} = \mathbf{0}$ . $\begin{bmatrix} 1 & 2 & 3 & 4 \\ 2 & 4 & 7 & 8 \end{bmatrix}$ $R2 \leftarrow R2 - 2R1$ : $$\begin{bmatrix} 1 & 2 & 3 & 4 \ 0 & 0 & 1 & 0 ...
