x + \frac{6}{x} = 18

x = 9 + 53, x = 9 - 53

Decimal Notation

x = 17.66025 \dots, x = 0.33974 \dots

Solution steps

x + \frac{6}{x} = 18

Multiply both sides by

x

x^{2} + 6 = 18 x

Solve

x^{2} + 6 = 18 x : x = 9 + 53, x = 9 - 53

x = 9 + 53, x = 9 - 53

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 9 + 53, x = 9 - 53

\frac{1}{2} + \frac{1}{3} = \frac{1}{x}

\frac{1}{x - 3} - \frac{3}{x ^{2} - 3 x} = 4

0 = 3 x^{2} - \frac{24}{x}

\frac{x}{x - 2} - \frac{9}{2 - x} = 2

0 = 1 - \frac{16}{x ^{2}}
