\frac{d}{d s} (\frac{s ^{2} - 4 s + 20}{s ^{2} + 6 s + 8})

\frac{10 s ^{2} - 24 s - 152}{( s ^{2} + 6 s + 8 ) ^{2}}

Solution steps

\frac{d}{d s} (\frac{s ^{2} - 4 s + 20}{s ^{2} + 6 s + 8})

Apply the Quotient Rule:

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

= \frac{\frac{d}{d s} ( s ^{2} - 4 s + 20 ) ( s ^{2} + 6 s + 8 ) - \frac{d}{d s} ( s ^{2} + 6 s + 8 ) ( s ^{2} - 4 s + 20 )}{( s ^{2} + 6 s + 8 ) ^{2}}

\frac{d}{d s} (s^{2} - 4 s + 20) = 2 s - 4

\frac{d}{d s} (s^{2} + 6 s + 8) = 2 s + 6

= \frac{( 2 s - 4 ) ( s ^{2} + 6 s + 8 ) - ( 2 s + 6 ) ( s ^{2} - 4 s + 20 )}{( s ^{2} + 6 s + 8 ) ^{2}}

Expand

(2 s - 4) (s^{2} + 6 s + 8) - (2 s + 6) (s^{2} - 4 s + 20) : 10 s^{2} - 24 s - 152

= \frac{10 s ^{2} - 24 s - 152}{( s ^{2} + 6 s + 8 ) ^{2}}

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

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

d er i v a t i v e ln (225 sin^{2} (x))

t an g e n t y = \frac{1}{x}

\int_{1}^{\infty} x^{- 3} d x
