\frac{d}{d x} (\frac{1}{x - a})

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

Solution steps

\frac{d}{d x} (\frac{1}{x - a})

Apply exponent rule:

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

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

Apply the chain rule:

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

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

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

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

Simplify

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