Can Any Polynomial of Degree Two Solve This Differential Equation?

Click For Summary
SUMMARY

The discussion centers on solving the differential equation {(\frac{d^2y}{dx^2})}^2 + ay(x) + b = 0. A key insight is the introduction of a new variable z(x) = y(x) + b/a, which simplifies the problem. The conclusion reached is that any polynomial of degree two can effectively solve this differential equation.

ok i figured it out
any polinom of degree two will do it
thanks
