Matrix Vector Product
1. **State the problem:**
We need to find all values of $k$ such that the product
$$[k \quad 1 \quad 1] \times \begin{bmatrix} 1 & 1 & 0 \\ 1 & 0 & 2 \\ 0 & 2 & -3 \end{bmatrix} \times \begin{bmatrix} k \\ 1 \\ 1 \end{bmatrix} = 0$$
2. **Rewrite the expression:**
Let $\mathbf{v} = \begin{bmatrix} k \\ 1 \\ 1 \end{bmatrix}$ and $\mathbf{w} = [k \quad 1 \quad 1]$. The expression is $\mathbf{w} \times A \times \mathbf{v} = 0$ where
$$A = \begin{bmatrix} 1 & 1 & 0 \\ 1 & 0 & 2 \\ 0 & 2 & -3 \end{bmatrix}$$
3. **Calculate $A \mathbf{v}$:**
$$A \mathbf{v} = \begin{bmatrix} 1 & 1 & 0 \\ 1 & 0 & 2 \\ 0 & 2 & -3 \end{bmatrix} \begin{bmatrix} k \\ 1 \\ 1 \end{bmatrix} = \begin{bmatrix} 1 \cdot k + 1 \cdot 1 + 0 \cdot 1 \\ 1 \cdot k + 0 \cdot 1 + 2 \cdot 1 \\ 0 \cdot k + 2 \cdot 1 + (-3) \cdot 1 \end{bmatrix} = \begin{bmatrix} k + 1 \\ k + 2 \\ 2 - 3 \end{bmatrix} = \begin{bmatrix} k + 1 \\ k + 2 \\ -1 \end{bmatrix}$$
4. **Calculate $\mathbf{w} (A \mathbf{v})$:**
$$[k \quad 1 \quad 1] \times \begin{bmatrix} k + 1 \\ k + 2 \\ -1 \end{bmatrix} = k(k + 1) + 1(k + 2) + 1(-1)$$
5. **Simplify the expression:**
$$k(k + 1) + (k + 2) - 1 = k^2 + k + k + 2 - 1 = k^2 + 2k + 1$$
6. **Set the expression equal to zero and solve for $k$:**
$$k^2 + 2k + 1 = 0$$
This is a quadratic equation which factors as:
$$ (k + 1)^2 = 0 $$
7. **Find the solution:**
$$k = -1$$
**Final answer:** The only value of $k$ that satisfies the equation is $\boxed{-1}$.
