- \frac{1}{x ^{2}} = - \frac{1}{7}

x = 7, x = - 7

Decimal Notation

x = 2.64575 \dots, x = - 2.64575 \dots

Solution steps

- \frac{1}{x ^{2}} = - \frac{1}{7}

Cross multiply

- 7 = - x^{2}

Solve

- 7 = - x^{2} : x = 7, x = - 7

x = 7, x = - 7

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 7, x = - 7

19.11969 = 19.62 x + (\frac{1.5}{3 x})^{2}

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

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

8 - \frac{2}{x ^{2}} = 0

\frac{2 x + 1}{x - 3} = 4
