h is linear with constant coefficients. d²y dx² = we will work on solving the corresponding homogeneous equation. The characteristic equation g m as your variable) is = 0 which has root = dy 10 dx ause this is a repeated root, we don't have much choice but to use the exponential function esponding to this root: to do reduction of order. = ue5ª (using the prime notation for the derivatives) +25y = x efore y₂ = plugging y2 into the left side of the differential equation, and reducing, we get y2 - 10y2 + 25y2 = -5x ow our equation is e5xu" = x. To solve for u we need only integrate xe irst constant of integration and b as the second we get " the general solution. twice, using a as
