\frac{d}{d x} (\frac{- 12 x}{( x ^{2} + 3 ) ^{2}})

- \frac{36 ( - x ^{2} + 1 )}{( x ^{2} + 3 ) ^{3}}

Solution steps

\frac{d}{d x} (\frac{- 12 x}{( x ^{2} + 3 ) ^{2}})

Simplify

\frac{- 12 x}{( x ^{2} + 3 ) ^{2}} : - \frac{12 x}{( x ^{2} + 3 ) ^{2}}

= \frac{d}{d x} (- \frac{12 x}{( x ^{2} + 3 ) ^{2}})

Take the constant out:

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

= - 12 \frac{d}{d x} (\frac{x}{( x ^{2} + 3 ) ^{2}})

Apply the Quotient Rule:

(\frac{f}{g})^{'} = \frac{f ^{'} \cdot g - g ^{'} \cdot f}{g ^{2}}

= - 12 \cdot \frac{\frac{d x}{d x} ( x ^{2} + 3 ) ^{2} - \frac{d}{d x} ( ( x ^{2} + 3 ) ^{2} ) x}{( ( x ^{2} + 3 ) ^{2} ) ^{2}}

\frac{d x}{d x} = 1

\frac{d}{d x} ((x^{2} + 3)^{2}) = 4 x (x^{2} + 3)

= - 12 \cdot \frac{1 \cdot ( x ^{2} + 3 ) ^{2} - 4 x ( x ^{2} + 3 ) x}{( ( x ^{2} + 3 ) ^{2} ) ^{2}}

Simplify

- 12 \cdot \frac{1 \cdot ( x ^{2} + 3 ) ^{2} - 4 x ( x ^{2} + 3 ) x}{( ( x ^{2} + 3 ) ^{2} ) ^{2}} : - \frac{36 ( - x ^{2} + 1 )}{( x ^{2} + 3 ) ^{3}}

= - \frac{36 ( - x ^{2} + 1 )}{( x ^{2} + 3 ) ^{3}}

2 x^{2} - 6 x + 3

\frac{\partial}{\partial x} (arccos (x y))

\int e^{- 3 x} tan (e^{- 3 x}) d x

\int_{2}^{3} \frac{27}{3 - x} d x

\int \frac{5 e ^{x}}{e ^{x} + 4} d x
