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

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

\frac{6 ( y + 1 )}{x ^{4}}

Solution steps

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

Treat

y

as a constant

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

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

Apply the Power Rule:

\frac{d}{d x} (x^{a}) = a \cdot x^{a - 1}

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

Simplify

- 2 (y + 1) (- 3 x^{- 3 - 1}) : \frac{6 ( y + 1 )}{x ^{4}}

= \frac{6 ( y + 1 )}{x ^{4}}
