Consider the system of differential equations y1 12y1 6y2
     Consider the system of differential equations  y_1\' = -12y_1 + 6y_2, y\' = -15y_1 + 6y_2, |  Rewrite this system as a matrix equation vector t y\' = A vector y  vector y\' = |  vector y  Compute the eigenvalues of the coefficient matrix Al and enter them as a comma separated list.   
  
  Solution
y1’ = -12y1 + 6y2
y2’ = -15y1 + 6y2
Matrix form = y’ = [-12 6] y
[-15 6]
Eigen values = -3 + 3i, -3 – 3i
