Schritte zur Lösung

x \to 2 lim (\frac{x ^{3} - 2 x ^{2} - 6 x + 12}{x ^{2} + 3 x - 10})

Vereinfache

\frac{x ^{3} - 2 x ^{2} - 6 x + 12}{x ^{2} + 3 x - 10} : \frac{x ^{2} - 6}{x + 5}

= x \to 2 lim (\frac{x ^{2} - 6}{x + 5})

Setze den Wert

x = 2

ein

= \frac{2 ^{2} - 6}{2 + 5}

Vereinfache

= - \frac{2}{7}

x \to \infty lim (4 e^{- x} + 6 x - 3)

x \to 0 lim ((1 + 6 x)^{\frac{1}{x}})

x \to 0 lim (\frac{2 x ^{2} + x}{5 x})

x \to 2 lim (\frac{( x - 2 )}{x - 2})

x \to 0 + lim (5 x ln (x))
