Higher Order Differential Equations?

[moonkhan2]

Solve the following Differential Equations:

1) y'' + 4y' + 4y = e^x

2) [ (D^2) - 7(D) + 12 ] y = cos(x)

Please, help me ...

Please, help me ...

What are the characteristic equations for these ODEs?

What are your thoughts?

Please share your work with us ...even if you know it is wrong

If you are stuck at the beginning tell us and we'll start with the definitions.
