erweitern (x^2+2x)((2x+2)e^{x^2+2x})

Lösung

erweitern

(x^{2} + 2 x) ((2 x + 2) e^{x^{2} + 2 x})

2 e^{x^{2} + 2 x} x^{3} + 6 e^{x^{2} + 2 x} x^{2} + 4 e^{x^{2} + 2 x} x

Schritte zur Lösung

(x^{2} + 2 x) ((2 x + 2) e^{x^{2} + 2 x})

= (x^{2} + 2 x) (e^{x^{2} + 2 x} (2 x + 2))

Wende das Distributivgesetz an:

a (b + c) = ab + a c

a = ((2 x + 2) e^{x^{2} + 2 x}), b = x^{2}, c = 2 x

= ((2 x + 2) e^{x^{2} + 2 x}) x^{2} + ((2 x + 2) e^{x^{2} + 2 x}) \cdot 2 x

= x^{2} (e^{x^{2} + 2 x} (2 x + 2)) + 2 x (e^{x^{2} + 2 x} (2 x + 2))

Vereinfache
