9 x^{2} - 4 = 0

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

Decimal Notation

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

Solution steps

9 x^{2} - 4 = 0

Move

4

to the right side

9 x^{2} = 4

Divide both sides by

9

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}

\frac{e ^{0} - e ^{- 0}}{2}

27 - m^{3}

12 + 9 x = - 6

n^{2}

(x + 1)^{2} - (y - 1)^{2}
