x^{- 3} - x = 0

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

Solution steps

x^{- 3} - x = 0

Refine

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

Multiply both sides by

x^{3}

1 - x^{4} = 0

Solve

1 - x^{4} = 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

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

\frac{25 - x ^{2}}{x ^{2} + 5 x} = 0

\frac{25 - x ^{2}}{x ^{2} + 5 x} = 1

\frac{13}{3} = \frac{26}{c}

\frac{x ^{2}}{1 + x ^{2}} = 0.83
