    the characteristic polynomial of the given matrix is

    (x - 1)(x + 3) + 5 = 0,

    hence the eigenvalues are -1 +/- i = a +/- bi, where a = -1 and b = 1.

    An eigenvector corresponding to -1 + i is [2 + i, 5], which has the form [x_1 + iy_1, x_2 + iy_2]

    where x_1 = 2, y_1 = 1, x_2 = 5, and y_2 = 0.

    Recall that the general solution has the form

    e^{at}( k_1 [ x_1 cos (bt) - y_1 sin (bt); x_2 cos (bt) - y_2 sin (bt)]

    + k_2 [y_1 cos (bt) + x_1 sin (bt); y_2 cos(bt) + x_2 sin (bt)])

    so the solution to our system of equations is

    e^{-t} ( k_1 [ 2 cos t - sin t; 5 cos t] + k_2 [cos t + 2 sin t; 5 sin t])

    where k_1, k_2 are arbitrary constants
