Substitute $y(x)={\displaystyle \underset{n=0}{\overset{}{}}}{a}_n{x}^2$ and the Maclaurn series for $4sinx$ into $y^{\text{'}}-xy=4sinx$ and equate the coefficients of like powers of x on both sides of the equation to find the first four nonvero lems in a power series expansion about $x=0$ of a general solution to the diferental equition

$y(x)=,$ cdots
