27 x^{2} - 12 = 0

x = \frac{2}{3}, x = - \frac{2}{3}

Decimal Notation

x = 0.66666 \dots, x = - 0.66666 \dots

Solution steps

27 x^{2} - 12 = 0

Move

12

to the right side

27 x^{2} = 12

Divide both sides by

27

x^{2} = \frac{4}{9}

For

x^{2} = f (a)

the solutions are

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

x = \frac{4}{9}, x = - \frac{4}{9}

\frac{4}{9} = \frac{2}{3}

- \frac{4}{9} = - \frac{2}{3}

x = \frac{2}{3}, x = - \frac{2}{3}

x^{3} - 25 x

20 x^{2} + 19 x + 3

- 21

x^{3} - 343 y^{3}

6 x + 16 = 3 x + 7
