Lösung

erweitern

3 x (x = - 1)

3 x^{2} = - 3 x

Schritte zur Lösung

3 x (x = - 1)

= 3 x (= x - 1)

Wende das Distributivgesetz an:

a (b - c) = ab - a c

a = 3 x, b = x =, c = 1

3 xx = - 3 x \cdot 1

3 xx = - 3 \cdot 1 \cdot x

Vereinfache

3 xx = - 3 \cdot 1 \cdot x : 3 x^{2} = - 3 x

3 x^{2} = - 3 x

e x p an d ln (3 \frac{x + 2}{x ^{4} ( x ^{2} - 4 )})

e x p an d a^{6} - b^{6} - 3 a^{2} b^{2} (a + b) (a - b)

e x p an d \frac{( 2 x - 8 ) ^{2}}{9}

e x p an d \frac{1}{2} + (x - \frac{1}{2}) e^{x}

e x p an d \frac{1 + 3 x}{( 1 + 2 x )}
