Second Order Homogenous

Okay geniuses this should be a walk in the park for you. Teach me how to find a second-order linear homogeneous equation that his this pair as a fundamental set of solutions.

y1(x)= x, y2(x)= x^2; I=(0,INF)

As a genius, I can see through your pathetic attempts to manipulate me by questioning my intelligence, and I refuse to participate in this thread.
