\frac{1}{x ^{2}} = 8

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

Decimal Notation

x = 0.35355 \dots, x = - 0.35355 \dots

Solution steps

\frac{1}{x ^{2}} = 8

Multiply both sides by

x^{2}

1 = 8 x^{2}

Solve

1 = 8 x^{2} : x = \frac{1}{2 2}, x = - \frac{1}{2 2}

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

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

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

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

4 x^{- 4} - 7 x^{- 2} - 36 = 0

\frac{2}{x + 2} + 2 = \frac{12}{x + 2}

3 + \frac{1}{x} = \frac{x}{7}

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