I worked this out and my solution to this is x(t) = -(t^2)/2 +2t - 2 +2.e^-t. Dont see why you'd have problems with solving this.
Where exactly do you need help with this ?

Hi,
A tutorial to support your query,

Differential Equations - Second Order DE's

In this chapter we will start looking at second order differential equations. We will concentrate mostly on constant coefficient second order differential equations. We will derive the solutions for homogeneous differential equations and we will use the methods of undetermined coefficients and...

Note:
In your case, consider 2nd order autonomous differential equation.
