Given t^2 y'' -t(t+2)y' = (t+2)y= 2t^3 and y1= t, y2= te^t(adsbygoogle = window.adsbygoogle || []).push({});

Find the particular solution-

I ve worked the problem to [ -2t^2 -2t] by:

-t * Integral [ 2t* te^t/ t^2e^t] + te^t * Integral [ 2t^2/ t^2e^t]

whereas the book states that it is simply -2t^2. Can you guys tell me where I made my mistake, I am stumped.
