derivative of

\frac{4}{2 x + 3}

- \frac{8}{( 2 x + 3 ) ^{2}}

Solution steps

\frac{d}{d x} (\frac{4}{2 x + 3})

Take the constant out:

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

= 4 \frac{d}{d x} (\frac{1}{2 x + 3})

Apply exponent rule:

\frac{1}{a} = a^{- 1}

= 4 \frac{d}{d x} ((2 x + 3)^{- 1})

Apply the chain rule:

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

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

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

= 4 (- \frac{1}{( 2 x + 3 ) ^{2}} \cdot 2)

Simplify

4 (- \frac{1}{( 2 x + 3 ) ^{2}} \cdot 2) : - \frac{8}{( 2 x + 3 ) ^{2}}

= - \frac{8}{( 2 x + 3 ) ^{2}}

\int \frac{x ^{3}}{5 x ^{2} + 3} d x

\int \frac{1}{( x ^{2} + 25 ) ^{3}} d x

\frac{\partial}{\partial x} ((3 x^{2} + 5 x + 1)^{\frac{3}{2}})

\int x \cdot \frac{5}{2} \cdot x^{2} + 7 d x

\int_{1}^{2} 3 x^{2} + 2 x + 1 d x
