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

\frac{3}{( 2 x + 1 ) ^{2}}

Solution steps

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

Take the constant out:

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

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

Apply the Quotient Rule:

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

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

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

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

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

Simplify

3 \cdot \frac{1 \cdot ( 2 x + 1 ) - 2 x}{( 2 x + 1 ) ^{2}} : \frac{3}{( 2 x + 1 ) ^{2}}

= \frac{3}{( 2 x + 1 ) ^{2}}

\int \frac{6 x + 5}{6 x ^{2}} d x

n = 1 \sum \infty - \frac{1}{n}

\frac{d}{d x} (x \cdot ln^{2} (x))

\int 4 cos (x) + 9 sin (x) d x

\int \frac{5}{( 3 x + 5 ) ^{4}} d x
