2. Find the particular solution of the following homogeneous second order linear differential equations: (i) d^2y/dx^2 + 2dy/dx + 5y = 0, y(0) = 1, dy/dx(0) = 1, (ii) d^2y/dx^2 - 10dy/dx + 25y = 0, y(0) = 2, dy/dx(0) = 8. Find the general solution of the inhomogeneous second order linear differential equation, d^2y/dx^2 - dy/dx + y = x^2 + 6.
