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

\frac{- 6 x ^{2} - 18 x - 8}{( 3 x ^{2} - 4 ) ^{2}}

Solution steps

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

Apply the Quotient Rule:

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

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

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

\frac{d}{d x} (3 x^{2} - 4) = 6 x

= \frac{2 ( 3 x ^{2} - 4 ) - 6 x ( 2 x + 3 )}{( 3 x ^{2} - 4 ) ^{2}}

Expand

2 (3 x^{2} - 4) - 6 x (2 x + 3) : - 6 x^{2} - 18 x - 8

= \frac{- 6 x ^{2} - 18 x - 8}{( 3 x ^{2} - 4 ) ^{2}}

(5 x - 4)^{4}, at x = 2

\int_{0}^{1} e^{- x} d x

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

\int 2 sin (d) x d x
