\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}})

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}}

\frac{\partial}{\partial x} (\frac{x y}{x ^{2} + 9})

\int 8 36 - 4 x - 32 d x

\int \frac{4 + 5 x}{1 + x ^{2}} d x

\frac{d}{d t} ((90 cos (\frac{π}{6})) t)

\int \frac{ln ( 21 x )}{x} d x
