Hi please can you help me to understand

Consider the initial value problem y\" 1221' +36y= 0, y(0) = 1, y'(0) = 0 (a) Let y = a)\". The characteristic equation is (b) The roots of the characteristic equation are A=_na Separate values with a comma. Use capital | for v\" 1. (c) A general solution is y=i II You must use capitial A and capital B as your constants of integration. Use real-valued functions. (d) The solution of the initial value problem is v=n@ Consider the initial 1value problem 3;" + 49' + 13y = 0, y(0) = 1, 31"(0) = 1 (a) Let y = a)\".
