Extracted text: Find the general solution of the differential equation except when the item stipulates otherwise. Write the complete and detailed solution 9. Given the equation [D' +6D° +9D² ]y=0 with the conditions that when x = 0, y = 0, y' = 0, y" = 6, and as x→0, y'→1, find the value of y when x = 1. Express your answer in its exact value.
