x^{-2}-5x^{-1}-6=0

x^{- 2} - 5 x^{- 1} - 6 = 0

x = - 1, x = \frac{1}{6}

Decimal Notation

x = - 1, x = 0.16666 \dots

Solution steps

x^{- 2} - 5 x^{- 1} - 6 = 0

Refine

\frac{1}{x ^{2}} - \frac{5}{x} - 6 = 0

Multiply by LCM

1 - 5 x - 6 x^{2} = 0

Solve

1 - 5 x - 6 x^{2} = 0 : x = - 1, x = \frac{1}{6}

x = - 1, x = \frac{1}{6}

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = - 1, x = \frac{1}{6}

\frac{4}{x} - \frac{9}{x + 1} = 2

41 y^{- 4} - 58 y^{- 2} + 1 = 0

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

\frac{9}{5} = \frac{1000}{x}

\frac{x}{0.12 + x} = \frac{1}{3}
