x->(-2(8+x^3))/((x^2-4))

Lösung

x - > \frac{- 2 ( 8 + x ^{3} )}{( x ^{2} - 4 )}

Lösung

x > 2

+1

Intervall-Notation

(2, \infty)

Schritte zur Lösung

x > \frac{- 2 ( 8 + x ^{3} )}{x ^{2} - 4}

Rewrite in standard form

\frac{3 x ^{3} - 4 x + 16}{x ^{2} - 4} > 0

Faktor

\frac{3 x ^{3} - 4 x + 16}{x ^{2} - 4} : \frac{( x + 2 ) ( 3 x ^{2} - 6 x + 8 )}{( x + 2 ) ( x - 2 )}

\frac{( x + 2 ) ( 3 x ^{2} - 6 x + 8 )}{( x + 2 ) ( x - 2 )} > 0
