Can I have some help with this

5. (12 points) Find the general solution to the following homogeneous second-order linear differ- ential equation: y\" + 49" + 4y = 0. Use variation of parameters to nd the solution to the following initial value problem ( on the interval (0, +00) )(no credit for using other methods): yr: + 4y: +49 = t_2,_2t. 9(1) = 0: ya) = 0
