erweitern 1/(2u^3)(u*1/2 x-v+u^3=0)

Lösung

erweitern

\frac{1}{2 u ^{3}} (u \cdot \frac{1}{2} x - v + u^{3} = 0)

\frac{x}{4 u ^{2}} - \frac{v}{2 u ^{3}} + \frac{1}{2} = 0

Schritte zur Lösung

\frac{1}{2 u ^{3}} (u \frac{1}{2} x - v + u^{3} = 0)

= \frac{1}{2 u ^{3}} (\frac{1}{2} ux - v + 0 = u^{3})
