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

x = 1 + 2, x = 1 - 2

Decimal Notation

x = 2.41421 \dots, x = - 0.41421 \dots

Solution steps

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

Multiply both sides by

x

x^{2} - 1 = 2 x

Solve

x^{2} - 1 = 2 x : x = 1 + 2, x = 1 - 2

x = 1 + 2, x = 1 - 2

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 1 + 2, x = 1 - 2

y = 2 y^{- 1} + 3 y^{4}

\frac{400}{x} = \frac{160}{x - 3}

\frac{x}{x - 8} = \frac{8}{x - 8} + 9

x, \frac{- 2}{5 x - 5 y} = 3

\frac{( x ^{4} - 1 )}{x ^{3}} = 0
