2. (a) Let **A** be a square matrix of order two which has eigenvectors \(\vec{u} = \begin{bmatrix} 2 \\ 3 \end{bmatrix}\) and \(\vec{v} = \begin{bmatrix} 4 \\ 1 \end{bmatrix}\) with corresponding eigenvalues \(\lambda = 2\) and \(\lambda = -5\).

Find exponential solutions \(\vec{X}(t) = \begin{bmatrix} x_1(t) \\ x_2(t) \end{bmatrix}\) of the system of differential equations \(\vec{X}' = \mathbf{A} \vec{X}\).

(b) How do \(x_1(t)\) and \(x_2(t)\) behave in the found solutions as \(t \to \infty\)?
