I'm having difficulty with my second derivative, I feel like I am missing a detail and it is messing me up!

Verify that the indicated family of functions is a solution of the given differential equation. Assume an appropriate interval I of definition for each solution.

Thus, in terms of x,
²-8dx + 16 =
+ 16(c₁e4x + c₂xe4x)
