\frac{d}{d x} (\frac{3 x + 36}{2 x + 18})

\frac{3 x + 72}{4 ( x + 18 ) x + 18}

Solution steps

\frac{d}{d x} (\frac{3 x + 36}{2 x + 18})

Take the constant out:

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

= \frac{1}{2} \frac{d}{d x} (\frac{3 x + 36}{x + 18})

Apply the Quotient Rule:

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

= \frac{1}{2} \cdot \frac{\frac{d}{d x} ( 3 x + 36 ) x + 18 - \frac{d}{d x} ( x + 18 ) ( 3 x + 36 )}{( x + 18 ) ^{2}}

\frac{d}{d x} (3 x + 36) = 3

\frac{d}{d x} (x + 18) = \frac{1}{2 x + 18}

= \frac{1}{2} \cdot \frac{3 x + 18 - \frac{1}{2 x + 18} ( 3 x + 36 )}{( x + 18 ) ^{2}}

Simplify

\frac{1}{2} \cdot \frac{3 x + 18 - \frac{1}{2 x + 18} ( 3 x + 36 )}{( x + 18 ) ^{2}} : \frac{3 x + 72}{4 ( x + 18 ) x + 18}

= \frac{3 x + 72}{4 ( x + 18 ) x + 18}
