L⁻¹{2x²x²−x }

Prendre la fraction partielle de 2x²x²−x : 2+2x−1

=L⁻¹{2+2x−1 }

Utiliser la propriété linéaire de la transformée inverse de Laplace :
Pour les fonctions f(s), g(s) et les constantes a, b: L⁻¹{a·f(s)+b·g(s)}=a·L⁻¹{f(s)}+b·L⁻¹{g(s)}

=L⁻¹{2}+L⁻¹{2x−1 }

L⁻¹{2}: 2δ(t)

L⁻¹{2x−1 }: 2e^t

=2δ(t)+2e^t
