Question: Solving differential equation

Dear all,

 

I am trying to solve a differential equation like the one below:

 

 

f := y(x)+5*(diff(y(x), x))+2*x^3*(eval(diff(y(x), x), x = 0))+3*y(0)

 

however, because of having y(0) in the quation, I get the error below:

Error, (in dsolve) found the indeterminate function y with different arguments {y(0), y(x)}

 

does anyone know how I could solve this?

Please Wait...
