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

x = 2, x = - 2

Decimal Notation

x = 1.41421 \dots, x = - 1.41421 \dots

Solution steps

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

Refine

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

Cross multiply

2 = x^{2}

Solve

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

x = 2, x = - 2

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = 2, x = - 2

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

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

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

r, p = \frac{3 s - r}{r q}

\frac{x}{x - 2} = \frac{4}{5}
