erweitern [2a^2(a^2-b^2)]m^2

Lösung

erweitern

[2 a^{2} (a^{2} - b^{2})] m^{2}

2 a^{4} m^{2} - 2 a^{2} b^{2} m^{2}

Schritte zur Lösung

(2 a^{2} (a^{2} - b^{2})) m^{2}

Entferne die Klammern:

(a) = a

= 2 a^{2} (a^{2} - b^{2}) m^{2}

= 2 a^{2} m^{2} (a^{2} - b^{2})

Wende das Distributivgesetz an:

a (b - c) = ab - a c

a = 2 a^{2} m^{2}, b = a^{2}, c = b^{2}

= 2 a^{2} m^{2} a^{2} - 2 a^{2} m^{2} b^{2}

= 2 a^{2} a^{2} m^{2} - 2 a^{2} b^{2} m^{2}

2 a^{2} a^{2} m^{2} = 2 a^{4} m^{2}

= 2 a^{4} m^{2} - 2 a^{2} b^{2} m^{2}
