Answer:
The complete solution is
 
 
Step-by-step explanation:
Given differential equation is
3y"- 8y' - 3y =4
The trial solution is 

Differentiating with respect to x

Again differentiating with respect to x

Putting the value of y, y' and y'' in left side of the differential equation


The auxiliary equation is




 
 
The complementary function is 
 
y''= D², y' = D
The given differential equation is
(3D²-8D-3D)y =4
⇒(3D+1)(D-3)y =4
Since the linear operation is
L(D) ≡ (3D+1)(D-3)    
For particular integral

      [since
    [since  ]
]
     [ replace D by 0 , since L(0)≠0]
      [ replace D by 0 , since L(0)≠0]
    
The complete solution is
y= C.F+P.I
