comment Problem with solution for non homogeneous differential equation
Thanks! Is there a way I can check this before I attempt to solve the entire solution?

@abel So I would need $y_p=Ax^2+Bx+C+Dxe^{2x}+Ee^{2x}$ ?

@Squirtle So the factorial function as we know it (defined over ℕ) is not continuous over ℝ?

@SherlockHolmes Thank you, I saw that question as I was searching. I read about the Gamma function, but I don't fully understand. I think it's because I don't fully understand how factorials and derivatives work (or don't work)

You mean $[T]_\beta^\gamma$? What would be the interpretation of this?

comment Understanding the change-of-coordinate matrix
Okay, I think I see what you mean. Thank you. So would $[T]_\beta$ mean the representation of $T$ with respect to the basis $\beta$?
