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

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

x = - 1, x = 2

Solution steps

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

Refine

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

Multiply both sides by

x

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

Solve

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

x = - 1, x = 2

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = - 1, x = 2

x, \frac{x + y}{x - y} = 0

\frac{2 x}{x - 3} = \frac{6}{x - 3} + 3

\frac{- 3 x + 1}{2 x - 7} = 2.1 (- 3 + 3)

3 = \frac{1}{x}

5 = \frac{8}{x} + 3
