derivative of

\frac{4 s}{s + 2}

\frac{8}{( s + 2 ) ^{2}}

Solution steps

\frac{d}{d s} (\frac{4 s}{s + 2})

Take the constant out:

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

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

Apply the Quotient Rule:

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

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

\frac{d s}{d s} = 1

\frac{d}{d s} (s + 2) = 1

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

Simplify

4 \cdot \frac{1 \cdot ( s + 2 ) - 1 \cdot s}{( s + 2 ) ^{2}} : \frac{8}{( s + 2 ) ^{2}}

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