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

\frac{6 x ^{2} + 4 x - 1}{x x}

Solution steps

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

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

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

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

Simplify

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

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

x^{2} \frac{d y}{d x} + sin (x) - y = 0

x \to + 0 lim (3 x^{2})

\frac{d y}{d x} = y sin (2 x)

\int \frac{3 a x}{b ^{2} + c ^{2} x ^{2}} d x

y^{^{'}} = 4 x - y
