\frac{d}{d x} (\frac{2 x ^{2} - 5 x}{3 x + 5})

\frac{6 x ^{2} + 20 x - 25}{( 3 x + 5 ) ^{2}}

Solution steps

\frac{d}{d x} (\frac{2 x ^{2} - 5 x}{3 x + 5})

Apply the Quotient Rule:

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

= \frac{\frac{d}{d x} ( 2 x ^{2} - 5 x ) ( 3 x + 5 ) - \frac{d}{d x} ( 3 x + 5 ) ( 2 x ^{2} - 5 x )}{( 3 x + 5 ) ^{2}}

\frac{d}{d x} (2 x^{2} - 5 x) = 4 x - 5

\frac{d}{d x} (3 x + 5) = 3

= \frac{( 4 x - 5 ) ( 3 x + 5 ) - 3 ( 2 x ^{2} - 5 x )}{( 3 x + 5 ) ^{2}}

Expand

(4 x - 5) (3 x + 5) - 3 (2 x^{2} - 5 x) : 6 x^{2} + 20 x - 25

= \frac{6 x ^{2} + 20 x - 25}{( 3 x + 5 ) ^{2}}

x \to 0 + lim (2^{\frac{1}{x}})

\frac{2}{s ( 1 + 3 s )}

x = - 2, x = 1, y = 6 x, y = x^{2} - 7

n = 1 \sum \infty n^{5} (1 + n^{6})^{2}

\int e^{- x^{2} - 2 x + 7} (x + 1) d x
