r^{2} - \frac{4}{9} = 0

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

Decimal Notation

r = 0.66666 \dots, r = - 0.66666 \dots

Solution steps

r^{2} - \frac{4}{9} = 0

Move

\frac{4}{9}

to the right side

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

For

x^{2} = f (a)

the solutions are

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

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

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

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

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

- 4 v^{2} + 8 v - 4 = 0

2 (2 u^{2} - 4 u) + 3 = 0

c^{2} = 4

x^{2} + 2 x = 300

2 x^{2} + 5 x - 11 = 0
