2 x - \frac{1}{x} = 0

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

Decimal Notation

x = 0.70710 \dots, x = - 0.70710 \dots

Solution steps

2 x - \frac{1}{x} = 0

Multiply both sides by

x

2 x^{2} - 1 = 0

Solve

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

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

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

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

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

\frac{7}{x - 3} = 0

\frac{x - 1}{x} = 0

\frac{4}{x} = \frac{x}{36}

\frac{( 2 x + 5 )}{( x + 4 )} = 1
