Solving 2nd Order Diff Eq in Quantum Mechanics

In summary, the conversation discusses a quantum mechanics problem that involves a differential equation. The person is having difficulty solving the equation with variable coefficients and is wondering if there is an alternative form or a way to reduce the order of the equation. The expert suggests looking at the solutions of the differential equation, which are related to the Hermite polynomials.

So I was trying a few quantum mechanics problems and encountered this diff eq:

[tex]\frac{\hbar^2}{2m}\frac{\partial^2}{\partialx^2}\psi(x) + \frac{1}{2}kx^2\psi(x) = E\psi(x)[/tex]

I put it into the form:

[tex]\frac{\partial^2}{\partialx^2}\psi(x) + (\frac{2mE}{\hbar^2} - \frac{m}{\hbar^2}kx^2)\psi(x) = 0[/tex]

But there is where I'm having difficulty. Is there an alternative form that would be easier to solve, or is there any way to reduce the order of the diff eq? I'm not used to second-orders with variable coefficients. Any guidance is greatly appreciated.

NOTE: k is an (apparently arbitrary) constant and has no quantum meaning in this context.
