\frac{d}{d x} (\frac{x ^{2} + 4 x + 13}{x + 2})

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

Solution steps

\frac{d}{d x} (\frac{x ^{2} + 4 x + 13}{x + 2})

Apply the Quotient Rule:

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

= \frac{\frac{d}{d x} ( x ^{2} + 4 x + 13 ) ( x + 2 ) - \frac{d}{d x} ( x + 2 ) ( x ^{2} + 4 x + 13 )}{( x + 2 ) ^{2}}

\frac{d}{d x} (x^{2} + 4 x + 13) = 2 x + 4

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

= \frac{( 2 x + 4 ) ( x + 2 ) - 1 \cdot ( x ^{2} + 4 x + 13 )}{( x + 2 ) ^{2}}

Simplify

\frac{( 2 x + 4 ) ( x + 2 ) - 1 \cdot ( x ^{2} + 4 x + 13 )}{( x + 2 ) ^{2}} : \frac{x ^{2} + 4 x - 5}{( x + 2 ) ^{2}}

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

\frac{\partial}{\partial x} (x^{2} + x y + y^{2} - 3 x + 2)

x \to - 3 lim (- x^{2} + 6 x - 5)

f (x) = - 2 sin (x), at x = \frac{π}{4}

\int \frac{y ^{3}}{y ^{2} + 4} d y

f (x) = 4 tan (x), at x = \frac{π}{4}
