Solution

simplify

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

Solution

a

Solution steps

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

Simplify

a^{- 1} - 1 : \frac{- a + 1}{a}

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

Apply the fraction rule:

\frac{a}{\frac{b}{c}} = \frac{a \cdot c}{b}

= \frac{( 1 - a ) a}{- a + 1}

Cancel

\frac{( 1 - a ) a}{- a + 1} : a

= a
