If $$x_2, x_1 < x_2$$ are the pair of values of x satisfying the matrix equation
$$\begin{bmatrix}1 & x & 1 \end{bmatrix} \begin{bmatrix}1 & 3 & 2 \\2 & 5 & 1\\15 & 3 & 2 \end{bmatrix} \begin{bmatrix}1 \\ 2 \\ x \end{bmatrix} = \begin{bmatrix}0 \\ 0 \\ 0 \end{bmatrix}$$, then $$\frac{x_1}{x_2} =$$

A

$$\frac{1}{5}$$

B

C

$$\frac{1}{7}$$

D

$$\frac{2}{5}$$
