Show that if y is a solution of (D^2+1)y=e^2x, then y is a solution of (D-2)(D^2+1)y=0. Solve both equations.

OpenStudy (usukidoll):

What I got so far... is that D = 2 so that would be c1e^2x

OpenStudy (usukidoll):

now for the (D^2+1) that's a complex root so when I took the quadratics... |dw:1382227946853:dw|
