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

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

Solution steps

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

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

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

Apply the Quotient Rule:

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

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

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

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

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

Simplify

- \frac{2 x ( x + 1 ) - 1 \cdot x ^{2}}{( x + 1 ) ^{2}} : - \frac{x ^{2} + 2 x}{( x + 1 ) ^{2}}

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

f (t) = \frac{2 t}{2 + t}

- cos (t)

x^{3} - x

\int (227 - x) - (23 + 0.7 x) d x

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