\frac{d}{d x} (\frac{4 x ^{2} + 4 x + 6}{x})

\frac{6 x ^{2} + 2 x - 3}{x x}

Solution steps

\frac{d}{d x} (\frac{4 x ^{2} + 4 x + 6}{x})

Apply the Quotient Rule:

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

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

\frac{d}{d x} (4 x^{2} + 4 x + 6) = 8 x + 4

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

= \frac{( 8 x + 4 ) x - \frac{1}{2 x} ( 4 x ^{2} + 4 x + 6 )}{( x ) ^{2}}

Simplify

\frac{( 8 x + 4 ) x - \frac{1}{2 x} ( 4 x ^{2} + 4 x + 6 )}{( x ) ^{2}} : \frac{6 x ^{2} + 2 x - 3}{x x}

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

\int_{3}^{6} (x^{2} - 2 x) d x

\int \frac{1}{( x ^{2} - 4 ) ^{2}} d x

f (x) = sin (tan (3 x))

- x^{2} + 2 x + 4, at x = 3

f (x) = \frac{4 x}{x ^{2} + 1}, at x = 1
