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

- \frac{20 x}{( 5 + x ^{2} ) ^{2}}

Solution steps

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

Apply the Quotient Rule:

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

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

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

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

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

Simplify

\frac{( - 2 x ) ( 5 + x ^{2} ) - 2 x ( 5 - x ^{2} )}{( 5 + x ^{2} ) ^{2}} : - \frac{20 x}{( 5 + x ^{2} ) ^{2}}

= - \frac{20 x}{( 5 + x ^{2} ) ^{2}}

\frac{\partial}{\partial x} (\frac{1}{6} x^{3})

f (x) = 2 x^{2} + 3 x - 2, (- 1, - 3)

\frac{d}{d x} (e^{x^{2} + x y})

\int \frac{1}{4 - x ^{2}} d x

9 x y^{^{'}} + y = 90 x
