81 x^{2} = 9

x = \frac{1}{3}, x = - \frac{1}{3}

Decimal Notation

x = 0.33333 \dots, x = - 0.33333 \dots

Solution steps

81 x^{2} = 9

Divide both sides by

81

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

For

x^{2} = f (a)

the solutions are

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

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

\frac{1}{9} = \frac{1}{3}

- \frac{1}{9} = - \frac{1}{3}

x = \frac{1}{3}, x = - \frac{1}{3}

- 3 x^{2} + 4 x

\frac{1}{8} \cdot 2

f = \frac{1}{3} \cdot 4^{3}

\frac{3}{2} + 6

3 x - 9 \geq 6
