erweitern-(x+2(ux))^2(xdu+udx)

Lösung

erweitern

- (x + 2 (ux))^{2} (x d u + u d x)

- x^{3} d u - 4 x^{3} u d u - 4 x^{3} u^{2} d u - x^{2} u d x - 4 x^{2} u^{2} d x - 4 x^{2} u^{3} d x

Schritte zur Lösung

- (x + 2 (ux))^{2} (x d u + u d x)

= - (x + 2 (xu))^{2} (x d u + u d x)

Wende das Distributivgesetz an:

a (b + c) = ab + a c

a = - (x + 2 (ux))^{2}, b = x d u, c = u d x

= - (x + 2 (ux))^{2} x d u + (- (x + 2 (ux))^{2}) u d x
