9 x^{- 4} - 10 x^{- 2} + 1 = 0

x = 3, x = - 3, x = 1, x = - 1

Solution steps

9 x^{- 4} - 10 x^{- 2} + 1 = 0

Refine

\frac{9}{x ^{4}} - \frac{10}{x ^{2}} + 1 = 0

Multiply by LCM

9 - 10 x^{2} + x^{4} = 0

Solve

9 - 10 x^{2} + x^{4} = 0 : x = 3, x = - 3, x = 1, x = - 1

x = 3, x = - 3, x = 1, x = - 1

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 3, x = - 3, x = 1, x = - 1

9 + \frac{2}{x - 1} = - \frac{4}{x - 2}

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

\frac{3}{x ^{2} + 5 x} = \frac{1}{2}

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

x + \frac{10}{x} = 6
