\frac{d}{d x} (\frac{x}{x ^{2} + 36})

\frac{36}{( x ^{2} + 36 ) x ^{2} + 36}

Solution steps

\frac{d}{d x} (\frac{x}{x ^{2} + 36})

Apply the Quotient Rule:

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

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

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

\frac{d}{d x} (x^{2} + 36) = \frac{x}{x ^{2} + 36}

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

Simplify

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

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