simplify (x^{-1}-2)^2

Solution

simplify

(x^{- 1} - 2)^{2}

Solution

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

Solution steps

(x^{- 1} - 2)^{2}

Simplify

x^{- 1} - 2 : \frac{- 2 x + 1}{x}

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

Apply exponent rule:

(\frac{a}{b})^{c} = \frac{a ^{c}}{b ^{c}}

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