1. Can anyone help me solve the below Laplace transform

y''-3y'-4y=-16x with y(0)=-4 and y' (0)=-5

Thank you.
2. What have you tried? Do you know how to take the Laplace of a derivative?
3. You have to transform both sides of the DE giving Remember that you can get this equation all in terms of and then do inverse.

It would be easier to just use the normal complementary function and particular integral method.
