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

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

Decimal Notation

x = 0.33333 \dots, x = - 0.33333 \dots, x = 1, x = - 1

Solution steps

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

Refine

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

Multiply by LCM

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

Solve

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

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

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

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

\frac{250}{200} = \frac{62.5}{x}

\frac{11.9}{x} = 3.14

\frac{x ^{3} - 1}{8 x} = 0

\frac{21}{3 x - 7} = 25

x = \frac{2 + 3 x ^{4} + 1}{( x ^{4} )}
