Solve the initial value problem. First make a substituion of the form t=x-a, then flind a solution ??,fnf' of the transformed differential equation. State the guaranteed interval of convergence.(-24x-x2)y''-6(x-2)y'-4y=0;y'(2)=0,y'(2)=7y(x)=(Type any series in summation notasion using n as the index variable and 0 as the starting index.)
