\frac{d}{d x} (\frac{k x + a}{b x + c})

\frac{- ab + c k}{( b x + c ) ^{2}}

Solution steps

\frac{d}{d x} (\frac{k x + a}{b x + c})

Apply the Quotient Rule:

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

= \frac{\frac{d}{d x} ( k x + a ) ( b x + c ) - \frac{d}{d x} ( b x + c ) ( k x + a )}{( b x + c ) ^{2}}

\frac{d}{d x} (k x + a) = k

\frac{d}{d x} (b x + c) = b

= \frac{k ( b x + c ) - b ( k x + a )}{( b x + c ) ^{2}}

Expand

k (b x + c) - b (k x + a) : - ab + c k

= \frac{- ab + c k}{( b x + c ) ^{2}}

\int ln (2 x + 1) d x

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

\int \frac{e ^{x}}{( 6 - e ^{x} ) ^{2}} d x

\frac{\partial}{\partial y} (x^{2} y^{4})

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