(\partial)/(\partial x)(1/((1-x)^2))

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

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

Solution steps

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

Apply exponent rule:

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

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

Apply the chain rule:

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

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

\frac{\partial}{\partial x} (1 - x) = - 1

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

Simplify

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