Question

Solve the system of differential equations given in matrix form for the general solution. We must do this by calculating the eigenvalues and eigenvectors. Note: we get a repeated eigenvalue and must solve for the second eigenvector to get two linearly independent solutions for our general solution. 

**Problem Statement:**

Solve the differential equation \(\dot{\mathbf{u}} = A\mathbf{u}\), where the matrix \(A\) is given by:

\[
A = \begin{pmatrix} -2 & 1 \\ -1 & 0 \end{pmatrix}
\]

**Explanation:**

This problem involves finding the solution to a system of linear differential equations. The vector \(\mathbf{u}\) is typically a function of time, and \(\dot{\mathbf{u}}\) represents the derivative of \(\mathbf{u}\) with respect to time. The matrix \(A\) represents the coefficients of the system. The task is to find the function \(\mathbf{u}(t)\) that satisfies this equation.
