x^{2} = 0.81

x = \frac{9}{10}, x = - \frac{9}{10}

Decimal Notation

x = 0.9, x = - 0.9

Solution steps

x^{2} = 0.81

For

x^{2} = f (a)

the solutions are

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

x = 0.81, x = - 0.81

0.81 = \frac{9}{10}

- 0.81 = - \frac{9}{10}

x = \frac{9}{10}, x = - \frac{9}{10}

x^{2} - 42 x + n = 0

\frac{1}{2} x^{2} - \frac{1}{4} x = 0

1 - (\frac{( 1 - 5 )}{2} x)^{2} - x^{2} = 0

- \frac{3}{2} x^{2} - 12 x + 54 = 0

- 3 x^{2} - 10 x + 16 = 0
