\frac{d}{d x} (\frac{- 2}{x})

\frac{2}{x ^{2}}

Solution steps

\frac{d}{d x} (\frac{- 2}{x})

Simplify

\frac{- 2}{x} : - \frac{2}{x}

= \frac{d}{d x} (- \frac{2}{x})

Take the constant out:

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

= - 2 \frac{d}{d x} (\frac{1}{x})

Apply exponent rule:

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

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

Apply the Power Rule:

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

= - 2 (- 1 \cdot x^{- 1 - 1})

Simplify

- 2 (- 1 \cdot x^{- 1 - 1}) : \frac{2}{x ^{2}}

= \frac{2}{x ^{2}}

\frac{d y}{d x} = 3 + 2 y

\int \frac{x}{x ^{2} - 16} d x

f (x) = x (x^{2} + 1)

(\frac{x}{x - 1})^{x}

y^{^{''}} + 4 y^{^{'}} - 45 y = 0
