x^{-2}-3x^{-1}+2=0

x^{- 2} - 3 x^{- 1} + 2 = 0

x = 1, x = \frac{1}{2}

Decimal Notation

x = 1, x = 0.5

Solution steps

x^{- 2} - 3 x^{- 1} + 2 = 0

Refine

\frac{1}{x ^{2}} - \frac{3}{x} + 2 = 0

Multiply by LCM

1 - 3 x + 2 x^{2} = 0

Solve

1 - 3 x + 2 x^{2} = 0 : x = 1, x = \frac{1}{2}

x = 1, x = \frac{1}{2}

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 1, x = \frac{1}{2}

0.08 = 1 - \frac{1127}{x}

\frac{1}{x} - \frac{1}{1 - x} = 2

\frac{20}{m} = 5

\frac{x - 3}{x + 7} = \frac{2}{5}

\frac{3}{x - 2} = - \frac{1}{x} - 2
