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

\frac{- x ^{4} - 2 x ^{3} + 6 x ^{2} + 12 x + 6}{( x ^{3} + 6 ) ^{2}}

Solution steps

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

Apply the Quotient Rule:

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

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

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

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

= \frac{( 2 x + 1 ) ( x ^{3} + 6 ) - 3 x ^{2} ( x ^{2} + x - 2 )}{( x ^{3} + 6 ) ^{2}}

Expand

(2 x + 1) (x^{3} + 6) - 3 x^{2} (x^{2} + x - 2) : - x^{4} - 2 x^{3} + 6 x^{2} + 12 x + 6

= \frac{- x ^{4} - 2 x ^{3} + 6 x ^{2} + 12 x + 6}{( x ^{3} + 6 ) ^{2}}

y, ln (x y 9) = x y

y = \frac{1}{2} x^{3} + 2, y = x + 1, x = 0, x = 2

x \to \infty lim (1 + \frac{2 ^{x + 1}}{2 ^{x} - 1})

\int \frac{3}{y 4 - ( ln ( y ) ) ^{2}} d y

n = 1 \sum \infty \frac{1}{( n + 7 ) n}
