DSolve returns with integration symbol, how to solve it? Thanks!

Hello, everyone! I am using DSolve to solve a differential equation which is somewhat complicated. After several tens of minutes of waiting, I got a result, but with integration symbol.

Result with integration symbol

and with unknown K1, K2, K3 as follows. unknown parameters K1, K2, K3

But when I use DSolve with simpler differential equations, I can get analytical result.

Analytical result for simpler differential equation

Will you please tell me how to get analytical result with my complicated eqation?

Thanks and best regards!

Thanks, Sean Clarke. I really did not see the details of DSolve. And I am not so familiar with the software.

The equation should be evaluatable because I can use every single part of the complicated equations for explicit solution.

I will try the FullSimplify and Assumption you provided.

Thanks again!
