2nd Order, Homog., Reduction of Order

Hey guys! I was assigned some work this weekend in my Applied Math I class where we are doing DEs.

This question is a two part problem. I understand how to do the second part, but I'm getting stuck on the first part.

The question is...

(x^2)(y'') + (x)(y') - (y) = 0
