Question
![Consider the following vectors:
\[
\mathbf{w}_1 = \begin{bmatrix} -1 \\ -2 \\ 1 \end{bmatrix}, \quad \mathbf{w}_2 = \begin{bmatrix} -8 \\ 5 \\ 2 \end{bmatrix}, \quad \mathbf{v} = \begin{bmatrix} -3 \\ 0 \\ -4 \end{bmatrix}
\]
The set \(\mathcal{B} = \{\mathbf{w}_1, \mathbf{w}_2\}\) is an orthogonal basis of a subspace \(W = \text{Span}(\mathbf{w}_1, \mathbf{w}_2)\) of \(\mathbb{R}^3\). Find a vector \(\mathbf{n}\) which is orthogonal to \(W\), and such that \(\mathbf{v} - \mathbf{n}\) is in \(W\).
Enter the vector \(\mathbf{n}\) in the form \([c_1, c_2, c_3]\):](https://content.bartleby.com/qna-images/question/cc6ab625-9bc8-400b-b1f4-23740d203705/ef05963a-46d4-46d4-9745-fd6f84562f97/8yhxuw_thumbnail.png)
