x^{- 2} + x + 8 x = 5

x \approx - 0.35023 \dots

Solution steps

x^{- 2} + x + 8 x = 5

Refine

\frac{1}{x ^{2}} + 9 x = 5

Multiply both sides by

x^{2}

1 + 9 x^{3} = 5 x^{2}

Solve

1 + 9 x^{3} = 5 x^{2} : x \approx - 0.35023 \dots

x \approx - 0.35023 \dots

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x \approx - 0.35023 \dots

(x) = - \frac{26}{x + 7}

\frac{24 - x}{x} = \frac{x}{36 - x}

2 + \frac{6}{y} = \frac{7}{5}

\frac{1}{( x + 1 ) ^{3}} = 0

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