derivative of

\frac{x ^{2}}{7 + 8 x}

\frac{14 x + 8 x ^{2}}{( 7 + 8 x ) ^{2}}

Solution steps

\frac{d}{d x} (\frac{x ^{2}}{7 + 8 x})

Apply the Quotient Rule:

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

= \frac{\frac{d}{d x} ( x ^{2} ) ( 7 + 8 x ) - \frac{d}{d x} ( 7 + 8 x ) x ^{2}}{( 7 + 8 x ) ^{2}}

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

\frac{d}{d x} (7 + 8 x) = 8

= \frac{2 x ( 7 + 8 x ) - 8 x ^{2}}{( 7 + 8 x ) ^{2}}

Expand

2 x (7 + 8 x) - 8 x^{2} : 14 x + 8 x^{2}

= \frac{14 x + 8 x ^{2}}{( 7 + 8 x ) ^{2}}

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

\int \frac{8}{( 1 + 4 t ) ^{2}} d t

\frac{d}{d x} (8 + x)

f (x) = ln (x), at x = 6

\frac{d}{d x} ((\frac{1}{x ^{2}} - \frac{3}{x ^{4}}) (x + 9 x^{3}))
