\frac{d}{d x} (\frac{12}{x + 1})

- \frac{12}{( x + 1 ) ^{2}}

Solution steps

\frac{d}{d x} (\frac{12}{x + 1})

Take the constant out:

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

= 12 \frac{d}{d x} (\frac{1}{x + 1})

Apply exponent rule:

\frac{1}{a} = a^{- 1}

= 12 \frac{d}{d x} ((x + 1)^{- 1})

Apply the chain rule:

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

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

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

= 12 (- \frac{1}{( x + 1 ) ^{2}} \cdot 1)

Simplify

12 (- \frac{1}{( x + 1 ) ^{2}} \cdot 1) : - \frac{12}{( x + 1 ) ^{2}}

= - \frac{12}{( x + 1 ) ^{2}}
