\frac{d}{d x} (\frac{5 x}{( x ^{2} + 2 ) ^{2}})

\frac{5 ( - 3 x ^{2} + 2 )}{( x ^{2} + 2 ) ^{3}}

Solution steps

\frac{d}{d x} (\frac{5 x}{( x ^{2} + 2 ) ^{2}})

Take the constant out:

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

= 5 \frac{d}{d x} (\frac{x}{( x ^{2} + 2 ) ^{2}})

Apply the Quotient Rule:

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

= 5 \cdot \frac{\frac{d x}{d x} ( x ^{2} + 2 ) ^{2} - \frac{d}{d x} ( ( x ^{2} + 2 ) ^{2} ) x}{( ( x ^{2} + 2 ) ^{2} ) ^{2}}

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

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

= 5 \cdot \frac{1 \cdot ( x ^{2} + 2 ) ^{2} - 4 x ( x ^{2} + 2 ) x}{( ( x ^{2} + 2 ) ^{2} ) ^{2}}

Simplify

5 \cdot \frac{1 \cdot ( x ^{2} + 2 ) ^{2} - 4 x ( x ^{2} + 2 ) x}{( ( x ^{2} + 2 ) ^{2} ) ^{2}} : \frac{5 ( - 3 x ^{2} + 2 )}{( x ^{2} + 2 ) ^{3}}

= \frac{5 ( - 3 x ^{2} + 2 )}{( x ^{2} + 2 ) ^{3}}

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

\int \frac{1}{x x ^{2} - 12} d x

\frac{d}{d x} (cos (x) sec^{2} (x))

\int \frac{2 - x ^{2}}{( x ^{3} - 6 x + 1 ) ^{5}} d x

\int (3 x - 1)^{4} d x
