![**Equation 21:**
\[ y'' - 2y' + 5y = e^x \cos(2x) \]
This is a second-order linear differential equation with constant coefficients and an exponential trigonometric forcing function. The left-hand side represents a homogeneous linear differential equation, while the right-hand side represents the non-homogeneous part, involving the product of an exponential function and a trigonometric function. Solving this type of equation typically involves finding the complementary (homogeneous) solution and particular (non-homogeneous) solution.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F6d6e0021-e2cc-4c08-9219-eb90d4e8405b%2Fb2c17acc-c2d6-4659-bc98-fd8e3000487b%2Fko3uoc9_processed.jpeg&w=3840&q=75)
