1-1/(x^2)=0.84

1 - \frac{1}{x ^{2}} = 0.84

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

Decimal Notation

x = 2.5, x = - 2.5

Solution steps

1 - \frac{1}{x ^{2}} = 0.84

Move

1

to the right side

- \frac{1}{x ^{2}} = - 0.16

Multiply both sides by

x^{2}

- 1 = - 0.16 x^{2}

Solve

- 1 = - 0.16 x^{2} : x = \frac{5}{2}, x = - \frac{5}{2}

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

Verify Solutions

Find undefined (singularity) points:

x = 0

Combine undefined points with solutions:

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

\frac{5 ( x - 4 ) - 6 ( x - 11 )}{3 x - 5} = 8

2 = Q + \frac{f}{b}

\frac{6}{x} + \frac{x}{2} = 4

\frac{6}{x - 8} = 3 x

- \frac{2}{x} = - \frac{5}{x - 6}
