\frac{d}{d x} (\frac{2}{x + 3})

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

Solution steps

\frac{d}{d x} (\frac{2}{x + 3})

Take the constant out:

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

= 2 \frac{d}{d x} (\frac{1}{x + 3})

Apply exponent rule:

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

= 2 \frac{d}{d x} ((x + 3)^{- 1})

Apply the chain rule:

- \frac{1}{( x + 3 ) ^{2}} \frac{d}{d x} (x + 3)

= - \frac{1}{( x + 3 ) ^{2}} \frac{d}{d x} (x + 3)

\frac{d}{d x} (x + 3) = 1

= 2 (- \frac{1}{( x + 3 ) ^{2}} \cdot 1)

Simplify

2 (- \frac{1}{( x + 3 ) ^{2}} \cdot 1) : - \frac{2}{( x + 3 ) ^{2}}

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