Question
**Consider the initial value problem:**

\[ y'' + y' - 12y = 0, \quad y(0) = \alpha, \quad y'(0) = 5 \]

**Find the value of \( \alpha \) so that the solution to the initial value problem approaches zero as \( t \to \infty \).**

\[ \alpha = \large \boxed{\phantom{000}} \]

**Explanation:**

In this problem, we are given a second-order linear differential equation with initial conditions. The goal is to determine the value of \( \alpha \), the initial value of \( y(t) \) at \( t = 0 \), such that the solution to the given differential equation approaches zero as \( t \) tends to infinity. This typically involves analyzing the characteristic equation of the differential equation, solving for the roots, and then using the initial conditions to find the specific solution that meets the criteria.
