81 x^{2} - 9 = 0

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

Decimal Notation

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

Solution steps

81 x^{2} - 9 = 0

Move

9

to the right side

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}

\frac{x + 2}{x + 3} \geq \frac{x + 1}{x - 2}

(x - 2)^{2} - 16 y^{2}

x^{4} + 64 x^{2}

2 (3 x + 1) \leq 20

3 x - 7 - 5 x = - 3 x + 2
