81 x^{2} = 16

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

Decimal Notation

x = 0.44444 \dots, x = - 0.44444 \dots

Solution steps

81 x^{2} = 16

Divide both sides by

81

x^{2} = \frac{16}{81}

For

x^{2} = f (a)

the solutions are

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

x = \frac{16}{81}, x = - \frac{16}{81}

\frac{16}{81} = \frac{4}{9}

- \frac{16}{81} = - \frac{4}{9}

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

1 x^{2} + 3 x + 2 = 0

x^{2} - x + 12 = 144

2 p^{2} - 10 p + 9 = 0

x, x = \frac{200 \cdot 0.07 \cdot 2 ^{2} \cdot ( 1 - x ) ^{2}}{5}

9 - 4 x^{2} = 0
