81 x^{2} = 1

x = \frac{1}{9}, x = - \frac{1}{9}

Decimal Notation

x = 0.11111 \dots, x = - 0.11111 \dots

Solution steps

81 x^{2} = 1

Divide both sides by

81

x^{2} = \frac{1}{81}

For

x^{2} = f (a)

the solutions are

x = f (a), - f (a)

x = \frac{1}{81}, x = - \frac{1}{81}

\frac{1}{81} = \frac{1}{9}

- \frac{1}{81} = - \frac{1}{9}

x = \frac{1}{9}, x = - \frac{1}{9}

c (x) = 1.2 x^{2} - 744 x + 123296

y^{2} + 14 y = 0

3 (x^{2} + 2) = 18

x^{2} - 2 x + 1 = 1

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