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

x = \frac{3 + 13}{2}, x = \frac{3 - 13}{2}

Decimal Notation

x = 3.30277 \dots, x = - 0.30277 \dots

Solution steps

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

Multiply both sides by

x

x^{2} - 1 = 3 x

Solve

x^{2} - 1 = 3 x : x = \frac{3 + 13}{2}, x = \frac{3 - 13}{2}

x = \frac{3 + 13}{2}, x = \frac{3 - 13}{2}

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = \frac{3 + 13}{2}, x = \frac{3 - 13}{2}

x + \frac{1}{x} = \frac{5}{2}

\frac{8}{6} = \frac{4}{x - 7}

\frac{3 y - 1}{2 y + 4} = \frac{4}{5}

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

\frac{6}{3 c} = \frac{2}{3}
