4 - 81 x^{2} = 0

x = \frac{2}{9}, x = - \frac{2}{9}

Decimal Notation

x = 0.22222 \dots, x = - 0.22222 \dots

Solution steps

4 - 81 x^{2} = 0

Move

4

to the right side

- 81 x^{2} = - 4

Divide both sides by

- 81

x^{2} = \frac{4}{81}

For

x^{2} = f (a)

the solutions are

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

x = \frac{4}{81}, x = - \frac{4}{81}

\frac{4}{81} = \frac{2}{9}

- \frac{4}{81} = - \frac{2}{9}

x = \frac{2}{9}, x = - \frac{2}{9}

m^{2} + 2 m - 120 = 0

2 x^{2} - 3 x + 1 = \frac{3}{8}

(x - 2)^{2} + (x + 8)^{2} = 1 0^{2}

3 x^{2} + 3 x = 25 x - x^{2}

5 x^{2} + 5 = - 15
