Wende die partielle Integration an

= [(x^{2} + 1) e^{x} - \int 2 x e^{x} d x]_{- 2}^{0}

\int 2 x e^{x} d x = 2 (e^{x} x - e^{x})

= [(x^{2} + 1) e^{x} - 2 (e^{x} x - e^{x})]_{- 2}^{0}

(x^{2} + 1) e^{x} - 2 (e^{x} x - e^{x}) : e^{x} x^{2} - 2 e^{x} x + 3 e^{x}

= [e^{x} x^{2} - 2 e^{x} x + 3 e^{x}]_{- 2}^{0}
