Wende Exponentenregel an:

\frac{1}{a} = a^{- 1}

= 3 y \frac{\partial}{\partial x} ((x^{2} + 2)^{- 1})

Wende die Kettenregel an:

- \frac{1}{( x ^{2} + 2 ) ^{2}} \frac{\partial}{\partial x} (x^{2} + 2)

= - \frac{1}{( x ^{2} + 2 ) ^{2}} \frac{\partial}{\partial x} (x^{2} + 2)

\frac{\partial}{\partial x} (x^{2} + 2) = 2 x

= 3 y (- \frac{1}{( x ^{2} + 2 ) ^{2}} \cdot 2 x)
