\frac{3}{x ^{2}} = 20

x = \frac{3}{2 5}, x = - \frac{3}{2 5}

Decimal Notation

x = 0.38729 \dots, x = - 0.38729 \dots

Solution steps

\frac{3}{x ^{2}} = 20

Multiply both sides by

x^{2}

3 = 20 x^{2}

Solve

3 = 20 x^{2} : x = \frac{3}{2 5}, x = - \frac{3}{2 5}

x = \frac{3}{2 5}, x = - \frac{3}{2 5}

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

x = \frac{3}{2 5}, x = - \frac{3}{2 5}

\frac{- 2}{x ^{3}} = 0

2 (1 + x)^{- 4} = 1

\frac{1}{2 x} = \frac{1}{4}

9 = \frac{18}{x}

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