I'm preparing for my final and came across a problem in the practice set which our professor didn't post the answers to... I tried to solve this question but failed to integrate $u_1'$ and $u_2'$. Here is the ODE: $$y''+y'-2y=\ln(x)$$

Could someone please help me with this? Thanks so much!!!

    It seems the integrals aren't elementary... [Here's](http://www.wolframalpha.com/input/?i=solve+y%27%27%2By%27-2y%3Dln+x) WA's solution.2012-05-08

    First find the solution to the corresponding homogeneous equation $y\prime\prime+y\prime-2y=0$ by using characteristic equation $r^2+r-2=0$2012-05-08
