0=(1-x^2)/(1+x^2)

Lösung

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

x = 1, x = - 1

Schritte zur Lösung

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

\frac{f ( x )}{g ( x )} = 0 \Rightarrow f (x) = 0

0 = 1 - x^{2}

Löse

0 = 1 - x^{2} : x = 1, x = - 1

x = 1, x = - 1

x = \frac{3 x}{x ^{2} - 5}

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

\frac{- 3 + m}{m - 2} = \frac{10}{3}

\frac{2}{x - 2} = \frac{8}{x + 13}

- 1200 + \frac{1350}{( 1 + x ) ^{2}} = 0
