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

x = 1, x = - 1, x = i, x = - i

Solution steps

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

Multiply both sides by

x^{2}

x^{4} - 1 = 0

Solve

x^{4} - 1 = 0 : x = 1, x = - 1, x = i, x = - i

x = 1, x = - 1, x = i, x = - i

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 1, x = - 1, x = i, x = - i

\frac{3}{x - 1} - \frac{1}{x} = 0

\frac{7}{3} = \frac{21}{x}

0.15 = \frac{75}{75 + x}

\frac{5}{x} = \frac{x}{20}

\frac{x}{x - 7} + 1 = \frac{7}{x - 7}
