hey guys:
x^2y''-(x^2+2x)y'+(x+2)y=x^3

Any help? Wolfram gives me a "no step by step available"

(yes please hold my hand)

is the first term x^(2*y'') or (x^2)*y'' ? if it's (x^2)*y'' it's y=-x^2; y'= -2x; y'' =-2

I think it is the second one.

The second one...although I did already submit this work (unfinished)...I would still be interested...maybe i just messed up the wolframalpha input.
