\frac{d}{d x} (7 - \frac{4}{x - 8} + \frac{2 x}{3 x + 1})

\frac{38 x ^{2} - 8 x + 132}{( x - 8 ) ^{2} ( 3 x + 1 ) ^{2}}

Solution steps

\frac{d}{d x} (7 - \frac{4}{x - 8} + \frac{2 x}{3 x + 1})

Simplify

7 - \frac{4}{x - 8} + \frac{2 x}{3 x + 1} : \frac{2 x ^{2} - 28 x - 4}{( x - 8 ) ( 3 x + 1 )} + 7

= \frac{d}{d x} (\frac{2 x ^{2} - 28 x - 4}{( x - 8 ) ( 3 x + 1 )} + 7)

Apply the Sum/Difference Rule:

(f \pm g)^{'} = f^{'} \pm g^{'}

= \frac{d}{d x} (\frac{2 x ^{2} - 28 x - 4}{( x - 8 ) ( 3 x + 1 )}) + \frac{d}{d x} (7)

\frac{d}{d x} (\frac{2 x ^{2} - 28 x - 4}{( x - 8 ) ( 3 x + 1 )}) = \frac{38 x ^{2} - 8 x + 132}{( x - 8 ) ^{2} ( 3 x + 1 ) ^{2}}

\frac{d}{d x} (7) = 0

= \frac{38 x ^{2} - 8 x + 132}{( x - 8 ) ^{2} ( 3 x + 1 ) ^{2}} + 0

Simplify

= \frac{38 x ^{2} - 8 x + 132}{( x - 8 ) ^{2} ( 3 x + 1 ) ^{2}}

\int v d v

\frac{d}{d x} (1000 (1 8^{3} - x)^{\frac{1}{3}})

x \to 6 + lim (x^{2} - 36)

8 (e^{x} cos (x) - e^{x} sin (x))

x \to - 1 lim (\frac{1}{x ^{3} - x})
