Consider the following 2nd-order linear non-homogeneous DE, y" + 3y -54y = 461 The complimentary solution of the equation is yc (x) = where ci and c2 are arbitrary constants. A particular solution of the equation is yp (x) = The general solution of the non-homogeneus equation is y (x) = The solution of the IVP of the above equation subject to the initial conditions y (0) = 3 and y [0] = 0 is y (x) =
