(x^3-8x^2)/(8-x)=1

Lösung

\frac{x ^{3} - 8 x ^{2}}{8 - x} = 1

x = i, x = - i

Schritte zur Lösung

\frac{x ^{3} - 8 x ^{2}}{8 - x} = 1

Vereinfache

\frac{x ^{3} - 8 x ^{2}}{8 - x} : - x^{2}

- x^{2} = 1

Löse

- x^{2} = 1 : x = i, x = - i

x = i, x = - i

\frac{6}{s + 5} + \frac{s - 5}{2} = 3

0 = \frac{1}{x} - 2

\frac{5}{x} + 13 = \frac{1}{x} + 3

so l v e f or x, a = \frac{3}{x + 2}

3 x + 2 = \frac{2 x ^{2} - 3 x + 2}{x - 2}
