Let's break out the quadratic formula. So the roots are going to be negative B, so it's negative 1 plus or minus the square root of B squared-- B squared is 1-- minus 4 times AC-- well A and C are both 1-- so it's just minus 4. eigenvector, ∂1, and the general solution is x = e 1t(c1∂1 +c2(t∂1 +λ)), where λ is a vector such that (A− 1I)λ = ∂1. (Such a vector λ always exists in this situation, and is unique up to addition of a multiple of ∂1.) The second caveat is that the eigenvalues may be non-real. They will then form a complex conjugate pair.
