Solution steps

One step at a time

L⁻¹{x²−4x−2 }

Take the partial fraction of x²−4x−2 : x+2

=L⁻¹{x+2}

Use the linearity property of Inverse Laplace Transform:
For functions f(s), g(s) and constants a, b: L⁻¹{a·f(s)+b·g(s)}=a·L⁻¹{f(s)}+b·L⁻¹{g(s)}

=L⁻¹{x}+L⁻¹{2}

L⁻¹{x}: δ′ (t)

L⁻¹{2}: 2δ(t)

=δ′ (t)+2δ(t)
