Given that the general solution of the equation y" - 9y = 0 is y, = get* + cred, use the method of undetermined coofficierts to solve the initial-value problem " - gy = 60/ }(0) =0. y'(0) = 0.Suppose In (x) = e" and y,(x) = xe are solutions of the equation y" + p(x)y + 7(x)y = . Find the general solution of the equation p" + p(xjy' + q(xly =
