- \frac{1}{x ^{2}} = - \frac{1}{40}

x = 210, x = - 210

Decimal Notation

x = 6.32455 \dots, x = - 6.32455 \dots

Solution steps

- \frac{1}{x ^{2}} = - \frac{1}{40}

Cross multiply

- 40 = - x^{2}

Solve

- 40 = - x^{2} : x = 210, x = - 210

x = 210, x = - 210

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 210, x = - 210

\frac{x}{x + 1} = \frac{9}{8}

a + 5 = \frac{7 a}{x}

\frac{1 - 2}{2 y - 19} = 0

\frac{864}{x} = \frac{288}{x}

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