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

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

Apply the chain rule:

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

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

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

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

Simplify

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

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